[coarse river]

it is not working since I used the list data

I tried removing it and directly return the dict but it didn't work

[mystic crater]

looks like that's your problem

you wrote this code?

[coarse river]

I wrote most of it and I took some bits feom stack overflow

[mystic crater]

Are you sure you are using .finditer correctly?

https://www.tutorialspoint.com/How-do-we-use-re-finditer-method-in-Python-regular-expression
check this out

[coarse river]

ohh

okay thank you I think I am going to try smthg

[mystic crater]

alright @ me if you run into any issues

[coarse river]

now I get "NotImplementedError"

[mystic crater]

on what part of the code?

[idle dew]

Two interfaces they cant have the same address network. Each interface have a address network specific

[frank star]

yea i got some help i fixed it

thank you tho 🙂 @idle dew

[coarse river]

okay now it is not printing anything 😭

[idle dew]

Good

[idle dew]

You're welcome

[mystic crater]

ok i think now the issue is with the actual regex pattern

[coarse river]

I think that I shouldnt be using the compiled function but I dont know how to change it

[tulip lagoon]

Hii everyone! Studying chemical engineering. Does someone know a good app/webpage to take notes? I've been using Goodnotes on iPad, but sometimes I prefer to use pc and I need something that have accessibility for both. Tried OneNote but its kinda basic for me I guess. Any recomendation? 🖤

[coarse river]

sry I don't

[tulip lagoon]

Awww ty anyways

[mystic crater]

import re

data = ["hi", "hello"]

regex = re.compile("^hello$")

res = []
for item in data:
    if(re.search(regex, item) != None):
        res.append(item)
    
print(res)

i did a little test here and it worked res had "hello" in it

[mystic crater]

you might wanna try the sciences channel

[tulip lagoon]

Yeah I'll try in some other channels tyyy

[coarse river]

But will it print the lenght of a def?

[mystic crater]

wdym def?

oh you mean the function

[coarse river]

the lenght of logs() needs to be == 979 if u use a list it will not print that right?

[mystic crater]

yeah the function returns the list so itll be checking the length of the list

[coarse river]

ohh ok ill try it

[mystic crater]

your logs() function returns the list data and when you do len(logs()) what you are actually doing is checking the length of the return value of the logs() function which is a list

also in regex you should put it in between quotations and it should start with a ^ and end with a $

[coarse river]

ohh okay got it

should every line begin with ^ and end with $?

or just the beginning and end of regex?

[mystic crater]

just the beginning and end

you should also include the \n (line break character) if there are multiple lines

https://www.regextester.com/
i recommend you play around with regex here to understand it better @coarse river

[coarse river]

tysm! I will check it out tomorrow I think I need to get used to using regex 😅
the code is still not working but I will try again tomorrow it's late now. good nightt

[mystic crater]

alright goodluck! but from what i can tell its giving back an empty list because the regex is not correct so it's not picking up the patterns

[coarse river]

ohh ok but it worked before that's the thing but anyway I ll try everything tmrw thanks again

you welcome

[elder trail]

I'm considering it, actually'

[elder trail]

Sounds esotheric

[fervent violet]

Hi guys, this is more theory and research based but How do you compare programming languages such as C# and R?

I have looked into compiler and abstraction so far but not sure where to go from there.

[elder trail]

both should have a function to measure process time, then you can compare, that how you can demonstrate (for example) that Python is waaaay slower than CPP or C

[idle dew]

It usually depends on your specific needs, target audience numbers, requested traffic.. etc

[fervent violet]

Compare and contrast the C# with the R programming language. Explain their design and implementation and how they relate to their intended use.

^ thats my question

[fervent violet]

yea done that as well

would talking about structure be okay for languages?

is the structure of the languages also their "design" ?

[little reef]

Hey guys anyone have their AP Comp Sci exam soon?

[pearl cedar]

For programming notes, I used to write markdown files in vscode - I like doing this as a minimal approach and I still create study guides in markdown. I recently switched over to notion for class notes. The major benefit is I can take screenshots in lecture (zoom class) and paste them into notion - and it has similar markdown functionality (like code blocks).

[blissful musk]

I don't know much about R so I will swap it out with python.

The main difference is in the compilation process. C# is compiled to bytecode, just like java. The bytecode is interpreted by the C# runtime (.NET), just like java bytecode is interpreted by the JVM, and just how python is interpreted, as is, by CPython. CPython is written in C/C++, so in a way python is written in C/C++. Therefore, you can actually call C++ modules directly from python scripts, though the overhead is much higher when you call them from the python runtime.

C#'s architecture and design pattern is much more 'traditional' OOP. Python is a more functional, scripty, messy type of OOP. People think a language is either functional or oop but they can be both. Python and javascript are great examples but most mainstream languages have examples of both. The key difference is that C# is strongly typed, so you need to explicitly state exactly what types functions expect as arguments, what they return, etc. For example, in python you may have a getAdminUsername function that takes an Admin object and returns their username. In python, if you pass in a User instead of an Admin, as long is they have a username, it will work. In C#, the program will not compile because you passed in the wrong type.

This seems trivial but it actually completely changes the way you code. In C# you cannot see if something works until you have set up all the types properly. It is super annoying if you just want to check something really quick, but on the other hand you get much more information just by hovering over stuff in your editor. On top of that, if you write something like 'typeof variable' in python, chances are you're going to get something vague like 'Object.' In C# you'll most likely get something much more specific.

Lastly, speed. Compiled languages are by nature faster. They can simply figure out more computations before runtime. That said, compiled python can be just as fast if not faster than c#

[fervent violet]

i see

what about just in time compilation

thats wat C# uses right?

[blissful musk]

The way to give python a chance at processing as fast as C# will involve doing a lot of messing around with the interpreter and the libraries you use. For example you can see just as good if not better performance to C# if you use the Cython library. That said, building a real app in Cython will be frustrating depending on what it is because a lot of libraries you want to use will be incompatible with Cython and you'll need to find ways to cast the types properly for cython to use

[fervent violet]

is that like flexibility / backwards compatability?

[blissful musk]

Yes JIT compilation is used in C# and it makes it extremely fast. It's basically a hybrid system where the program compiles as it runs because it gets more and more information. Once the types are more and more solidified, the runtime (.NET) can compile more of your code in advance

yeah like lets say you pass a certain type of high level you retrieve from an API into some CPython computation. That API decides to change the return types of its data to different types of integers. All of your code will be broken

Sorry Cython, not CPython**

As a side note to JIT, it takes a ton of advantage of caching so it also checks there to see if theres any information it can use to learn more in advance about how your program will run

[fervent violet]

hmm this is too much for me lol

still first year

[blissful musk]

Haha it is complicated but being exposed to it more times will always help

[fervent violet]

yeah

[blissful musk]

this is pretty advanced stuff, I mean nobody outside of python devs would have any idea what im talking about

[fervent violet]

ive briefly compared them

[blissful musk]

the c# is slightly more common knowledge

[fervent violet]

yeah

i dont get many results for R

[blissful musk]

R is very niche to data science

[fervent violet]

its aparently mostly used by data scientists

yes

[blissful musk]

yeah python is also very common for data science

[fervent violet]

yea

[blissful musk]

but more for data science applications and software and less for actual scientists

[elder trail]

Guys I finally feel that I'm making improvements on Data structures, at least at a theorical level

😃

[rotund grove]

Awesome

[whole sonnet]

what language would you guys best recommend for competitive coding?

[twin fox]

c++

all competitive programmers i've watched use it

[whole sonnet]

oh,,,,thanks

[idle dew]

java or python

[idle dew]

c++

Anyone got a recommendation for learning unity resources perhaps?

[finite ridge]

udemy has some good ones, if you aren't a beginner to programming try "unity in action" by joe hocking

its on z-library

[idle dew]

👋 hello, front-end junior / mid senior dev here. I'm all in ears for any type of web dev or coding related questions just wanted to say hi

[spare ocean]

[mystic crater]

Firstly Hi :)) Secondly since you proposed, I intend to work as a front-end developer soon and right now Im good with vanilla css html js and vue, what should my next step be? I was thinking react.js

[idle dew]

Oh hey, excelent question. You may want to learn react for a next step. It already consists some of the vue functionalities already built-in but also It's waay more hyped right now. If it was like 2 years ago, people would be argue about vue / react / angular combo but at the time I see react has a clear ahead.

I would suggest you to go onto the back-end devlopment basics too. React and axios / apollo would be a guarantee portfolio project.

And lastly I'm currently working with Nextjs which is a react child framework. It's really good and hyped at this moment of time

[spare ocean]

I will highly recommend you learn TypeScript firstly, imo its must have skill in 2021

https://github.com/enaqx/awesome-react#react-and-typescript and for react

[mystic crater]

Alright then ill go with react, I already know backend but havent really practiced it too much

[mystic crater]

Honestly ive been putting it off for awhile but i really should get to it, along with something like SASS or SCSS

[spare ocean]

on real projects, typed app is very much loved, so TypeScript is really very good and will increase your qualification 🙂

[idle dew]

TypeScript is the future lol

[spare ocean]

and it will also speed up your development, because you will not have a "black" box, the intelliSense in the editor will help you perfectly, because you type each object into an interface or type.

you will know what you want to get from another component or from the server

[idle dew]

Marwanos you should choose a project to work on. SCSS SASS BootStrap and Tailwind MaterialUI are the main to go with your styling. React Next Hooks Nextjs is the logic based and lastly you can dip your toes into the backend aspect all of these too, the basic understanding is required

[spare ocean]

Yes, and don't forget to go to the repository above

[idle dew]

Hooks(as a concept)

[spare ocean]

Hooks are amazing too, yep

[idle dew]

We wish you luck and here to answer questions

[mystic crater]

Thanks guys you gave me some ideas for my summer project hehe

[mystic crater]

will do!

[grim vale]

Anyone have any experience with Jenkins & Jenkinsfiles?

Trying to run a jenkins job from another pipeline & passing in two params at two different stages

stage('pipelineA') {
  steps { 
    build job: 'pipelineA', parameters: [
      string(name: 'aws-genesis-prod', value: 'aws-genesis-prod')
    ]
}

But uh, nothing happens

[idle dew]

I have so many problems with jenkins all the time so I really cant tell sorry...

[grim vale]

yeah I just started learning it

[zenith mason]

Hey guys ! actually finishing a personal Fullstack MERN project, i would like to deploy it, do you know what's the easiest / fastest way to deploy it ? aws looks sooo painfull to do x)

[lusty linden]

Hi guys, wondering if some base knowledge of computer science is necessary before learning a programming language like Python?

[idle dew]

Hey Ishhin, I would give Vercel a shot to deploy it. I don't know it would be compatible or not.

[proven arch]

I'm only in highschool for computer science but I highly doubt so! Learning syntax especially for a language like python is easy n something you can pick up along the way

If you can pick up a python textbook you can probably go pretty far with just that

[lusty linden]

@proven arch roger that, thank you. I may do a bit of research on how it actually works though 😛

[proven arch]

Good idea : P

[zenith mason]

@idle dew Cheers man, i'll look for that 🙂

[open cairn]

Not necessary but it surely helps espesially when you encounter problems, knowing how things work really saves your time. But if you are a beginner, you should focus on learning how to write Python first.

[spare ocean]

i also deployed at github pages

[lusty linden]

@open cairn roger that mate

[mystic crater]

You'll learn the cs topics as you learn python as long as you follow a guide that explains what the code you're writing does and whenever you don't understand something look it up

[lusty linden]

@mystic crater I've got the udemy python bootcamp - is this the way to go?

[mystic crater]

I haven't tried it but udemy usually is a reliable source so ig

[onyx nest]

Anyone understand how works Linked list in C language?

[rustic mesa]

It's been a while since I've used them specifically in C. But what is the problem you're having?

[idle dew]

I'm part fluent in C, list are arrays with memory direction keys between elements

What can i help with

[onyx nest]

Well I have file with some text and I need to save from line every word to Linked list.

So each element in the list will be word

[idle dew]

It is a txt?

[onyx nest]

yes

[idle dew]

https://stackoverflow.com/questions/40592846/writing-data-from-a-linked-list-to-a-txt-file-in-c

Take a look here, its a basic example

Otherwise dm your code and I'll take a look

[onyx nest]

Alright I will look and if I will have some trouble Ill dm you

[idle dew]

Sure!

[little reef]

Hey! I'm having a bit of trouble on this problem.

[narrow root]

Anyone can recomend me a book/web/tool... to learn java script

I actually programme at python

[meager sorrel]

Check out the "Try it Yourself" section here: https://www.w3schools.com/java/ref_keyword_extends.asp

The key concept here is inheritance and that the child class that extends the parent (B extending A) can overwrite methods of the parent class and they end up getting called instead of the parent method. Even though you declare the class on the left as a type "A", it still has the child methods because you instantiate it as "B".

It's easier if you think of "A" as vehicle and "B" as car. Although you can call your car a "vehicle," it's more specific to call it a "Ford Mustang". And although all vehicles honk, it honks in a way specific to a "Ford Mustang."

[hushed pecan]

Hi everyone! I'm currently a professor of game dev, but I'm planning to go back to being a freelance full-stack developer. Since I've been teaching full time for 4 years now, I believe my current tech stack is a bit outdated. What language or platform can you guys suggest that I take a look into and study?

I used to be a native android and asp.net core developer for 3 years, but I believe the market is leaning towards react, nodejs, etc

[idle dew]

Flutter 2 and React-Native is on the rise right now for mobile/web cross platform

I would suggest you to look into Flutter 2 especially

[hushed pecan]

Oh, yeah. I was looking into both platforms recently. Thanks for the tip! I'll grab a Udemy course for a quick study then.

[little reef]

Thank you!

[past mauve]

Create 2 boolean variables to check when you are entering a continuous stream of 1s or 0s, and set them to true when you come across more than 2 1s/0s in a row, and set them back to false otherwise.

And create another 2 sets of int variables to store the index of where you set the boolean values to true and false respectively. That way you have the exact locations of the positions where you started and ended

[lone wolf]

@jolly crow so when it comes to for and while loops, they each have different purposes

[past mauve]

I'm interested in getting into Full-Stack development, can anyone suggest me a good online course?

[warm rampart]

what's your experience level?

[jolly crow]

Ok I have my notebook ill write down the notes ~

[past mauve]

I'm good with basic JS HTML and CSS, and know my way around SQL (MySQL specifically)

Don't know any JS frameworks tho

[warm rampart]

full-stack development uses quite a lot of technologies in the background so if you're already at a point where you can use HTML/SCSS/JS to set up the front-end then you'll need to move on to learning things like PHP,SQL,AJAX, NPM, and maybe WordPress. Depending on what kind of things you want to be making

[idle dew]

@past mauve You can check traversymedia in youtube and also please check some actual projects to work on.

[warm rampart]

There are also options for using more fully fledged environments like Django in Python if that's more your taste

[azure pawn]

just iterate over each bit of the std::vector<bool>

[lone wolf]

While loops are generally used as a way of looping until you've met a specific condition, while for loops don't need to meet a condition. for loops can also be used as iterators to handle data in a more efficient way, like if you want to get a specific property from each object in a set, you could do [i.property for i in dataset]

[past mauve]

I'm good with Python, but I hear that Django uses NoSQL for its databases right?

[azure pawn]

depends on the stack you wanna learn

[past mauve]

Ahh so there are different stacks too 🥴

[azure pawn]

mainly mern or mean

[warm rampart]

as far as i'm aware you can use lots of the different versions of SQL with Django, you aren't restricted to one i believe

[jolly crow]

Ohhh I see!! But what about the "i" that is often used in questions is it a default thing or just a variable?

[lone wolf]

When I was using Django it used SQLite for its databases

[jolly crow]

In the while loop

[dull raven]

Hey guys, does anyone know how to update from high sierra to catalina? I have an early 2011 and the system won't let me update

[past mauve]

Afaik it uses MongoDB now...

[past mauve]

And what are MERN and MEAN 😅

[azure pawn]

Mern : MongoDB, Express, React, NodeJS
Mean : replace react with Angular

[warm rampart]

people tend to use the notation "i" inside of a for loop as it represents either the number or iterations or the current object you're iterating over. For example, in java you'd see something like:

for {some_list; i<20; i++}
Where "i" denotes the iteration

[lone wolf]

the i could be anything - you're telling the for loop that you're looking for something, and you're specifying a name for what you're looking for. In my own scripts I've used i for convenience a lot, but I'll also go into specifics like [key.value for key in dataset] if I'm writing unclean code :)

[tacit kite]

Just store in 2 arrays of booleans then. No need for more variables

[warm rampart]

@jolly crow did you say you were working on Python?

[jolly crow]

I get it know, thank you so much!!!

Yes

Python

[warm rampart]

because for Python you'd usually use the notation in for to represent a variable/piece of information you want to operate on inside of a list

[past mauve]

Does the Django stack require JavaScript too? As in stuff like Node, React and Angular

[warm rampart]

so you'd put something like:
for char in string:

operation you want to do on the char
or
for item in some_list:
operation you want to do on the item

[jolly crow]

Yes I got confused and thought it was a like a mandatory to have due to the exercises only having the "i" as a variable, now I'll try the exercises of the loops to remember the information

[azure pawn]

a good practice : don't use i and j for iterations

[past mauve]

Lol why

[warm rampart]

it depends, sometimes it's fine

[jolly crow]

Okay!! I'll update you on the progress, I really appreciate your help!

[azure pawn]

sometimes when refactoring code it can be confusing

[past mauve]

I use i and j exclusively for iterations and never anywhere else

[warm rampart]

you're welcome, best of luck

[past mauve]

Ahh makes sense

[warm rampart]

this was me learning java honestly

[lone wolf]

honestly in a professional environment (just from a python standpoint) i is used really commonly for iterations

[warm rampart]

^^

[lone wolf]

I can definitely see how in .net or other lower level languages the refactoring is an issue but since Python is such a high-level language there isn't much of a problem. Python also isn't generally refactored as much in DevOps, when code goes to prod it's expected to follow best practice and formatting, otherwise it generally has to be revised lol

[warm rampart]

yeah i can't recall the last time i didn't send something off without linting it

[past mauve]

Alright, so finally, if I want to learn the MERN stack, can someone recommend me a good course?

[azure pawn]

yeah True yeah i do agree but the whole idea is to make the code as readable as possible

for each their own , i worked with a guy who doesn't use 'else' statements

[warm rampart]

that's just irritating

[azure pawn]

yeah but he was convinced nested if are useless

[warm rampart]

what language did he work in?

[azure pawn]

python

[past mauve]

Did he at least use elif?

[warm rampart]

oh god he probably suffers when he sees code that goes out like:
else:
pass
return something

[azure pawn]

he just reversed the last else

than proceeds for continuious ifs

[past mauve]

Hilarious

[warm rampart]

so does he not use elifs?

[azure pawn]

no not really

[warm rampart]

weirdo

[lone wolf]

That hurts my brain

[past mauve]

Doesn't that slow down the program though?

Like if you have to check each condition then it'll take longer right?

[azure pawn]

he's fast but his code was spaghetti

[warm rampart]

it just makes it less readable for the most part

really bad for maintenance

[azure pawn]

reminds me when i used to love goto in C

[lone wolf]

He's the kind of person who doesn't use case in c++

[warm rampart]

case is fantastic tho

[past mauve]

Switch case is the one thing I wish Python had that other languages have

Otherwise Python is perfect

[lone wolf]

Absolutely

[warm rampart]

tbf i still want python to have ++

bc +=1 annoys me

[past mauve]

That too

[tacit kite]

In some low level, like C, its quite common too

[lone wolf]

I do a lot of intelligence analysis and having to work with data without switch/case is something that really has made me want to learn more C++

[warm rampart]

I might revisit C++, i only used it briefly years ago to make a simple text-based game when i was like 19

i bet that code was awful

[lone wolf]

Lmao, I used it awhile ago to make a discord bot but after that I just dumped it

[azure pawn]

you never want to edit an already working C code

[warm rampart]

back in the days Eclipse was considered a good IDE

[past mauve]

Lol

[lone wolf]

I really love pythonic solutions to problems but damn, if we made such big changed from 2..x to 3.x I hope 4.x comes with ++ and switch/case....

[past mauve]

I used to use Eclipse

[lone wolf]

Back in the day VS was a bad IDE 😩

[past mauve]

Back in school

[warm rampart]

now VS is insanely good

[past mauve]

VS still is bad lol
VS Code is the good one

[azure pawn]

well vim is still the king

[lone wolf]

Shh.... the first one doesn't exist

[past mauve]

Noooo let's not start editor wars now

[warm rampart]

i use it where i can but sometimes i need to use other stuff

[tacit kite]

I dont agree with that. Maybe that can be true in a few cases.

[warm rampart]

i do love vim though

[past mauve]

Pleams emacs

[warm rampart]

do we have any people into building keyboards here

[past mauve]

As in like PCBs for keyboards and all?

[warm rampart]

not building the components themselves, just assembly and tweaking and modifying

like buying case,PCB, Switches,Plate,Padding,Lube,Keycaps and everything

soldering it all

[twin fox]

Should've made it in JS or Python and save yourself the headache lol

[warm rampart]

tbf you can be way more efficient with lower level languages for stuff like that

[lone wolf]

The point was to learn it and give myself a headache lol. Before that I made a couple community bots in Python and NodeJS 😄

[past mauve]

Aight Imma head out, nice hanging out

[warm rampart]

later dude

[lone wolf]

Seeya man :)

[warm rampart]

this the one i made ^^

[tacit kite]

Looks cleean

Does anybody know how to make arrays work in constructors in Java?

[unkempt trail]

how could jvscholz sounds so crispy clear no buzz even though his mouth is far away from the mic? is it because of the mic quality or theres some setting?

[finite rapids]

whats the best language to learn for starters ?

[whole imp]

python is very simple to pick up and the room for expanding with it is endless, still used for big projects too

[finite rapids]

is it possible to learn it in only a laptop and not much of a big setup?

[whole imp]

yes! plenty of tutorials on youtube also if you'd like to learn

went through first and second year computer science with a toaster of a laptop just fine lol

[violet tundra]

what is the use of super().init()while creating a inherited class?, bruh discord converts lowecases to italics, but you know what i'm saying

[finite rapids]

oh i see, thank you!

[whole imp]

the use of super() will allow you to override a method that you've made, so super().init() will override your init() method (if you've made another)

not sure if i botched that explanation

https://www.educative.io/edpresso/what-is-super-in-python

[violet tundra]

right, kinda get what you're trynna say, so like say if i've created a child class which inherits two classes say classA and classB, also both the classes inherit a Base class, so when i create a object of the child, in order to avoid the Base dunder being called twice, super() helps you with that, right

[whole imp]

yes

[violet tundra]

cool, thanks a lot

[timid nymph]

how to start localhost/8080 ?

[whole imp]

are you making a webserver or something

[violet tundra]

umm, what server are you trynna host on?

[timid nymph]

my local server

[violet tundra]

node based?

that's all i know, hope a web dev can answer this

Here's a basic example of web server

[timid nymph]

tnx

[violet tundra]

yooo fire🔥

[open mural]

XD

it might be filled with errors since its been awhile

[whole imp]

when i did my web development module, i used XAMPP and it made running webservers a lot easier

has Apache in addition to allowing for databases, php etc

[open mural]

it is advisable to go for XAMPP/apache/nginx etc if you are working on production critical application how ever if you want to learn network programming(ie sockets ) programming it will be a good expirience in my opinion

[whole imp]

just depends what you're using the server for, but yes @open mural is speaking facts

[open mural]

here's an example in c++ please note that this example may contain memory leaks as im not good with low level programming

[little reef]

Please help with this

[gleaming dragon]

Does anyone know if James pc set up is a modern setup that just looks old?

[grim vale]

he has a 1060

and some pretty modern cpu that I don't remember

but you can just read the description like the text on screen tells you to

[mystic crater]

B

oh actually it could be E i honestly forgot if java is pass by reference or value

[little reef]

The answer key says its E and I have no clue how

[gleaming dragon]

I looked into but it just says the monitor not the desktop

[mystic crater]

yeah so whats happening is the array you are passing to changeIT is not being changed

[little reef]

So changeIt doesn't effect the code?

[mystic crater]

it creates its own array but doesnt affect the array being passed to it (nums)

its because nums is being passed to changeIt by value, as in we pass a copy and the original will still be intact afterwards

[little reef]

Thank you so much

[whole imp]

its E if you're wondering

marwanos explanation is correct

java does pass by value

[regal quartz]

sorry being a bit pedantic but you don't pass in a copy of the array, you pass in the reference to the array which will get stored in arr, so modifying arr in the method would in fact modify the original array. since you overwrite arr with a reference to a new array in the method, the original array doesn't get modified

[mystic crater]

ahh right i see what you're saying im a bit rusty at java and id always get confused if it is passed by reference or value. Anw id have to try it out myself if i want to be 100% sure. Thanks for the clarification. @little reef the answer is still the same but the reason is different see schwoop's comment I believe they're right.

[little reef]

Thank you all, just cramming for the AP test tomorrow

[mystic crater]

good luck!

[elder trail]

Hi guys

Hows it goin

[haughty harness]

Finals week and I’m dying lmao

Currently trying to force myself out of bed to grind

[elder trail]

Finally understood basic sorting methods (bubbleSort) so I'm feeling kinda happy

I'm goin slow but safe

[little reef]

Kind of confused with the result after each sort

[idle dew]

It works just fine

[shadow pagoda]

beginner python question --

is my way better or how much does it matter here?

[little reef]

No I have to find when j = 2 what happens

Ik it works just not sure how

[idle dew]

you're ok

[elder trail]

Is bubbleSort i think, can anyone correct me?

[open mural]

more than enough

b=''
for i in range(0,len(stri)):
    if(i==n):
        continue
    else:
        b=b+stri[i]

return b

@shadow pagoda if you dont want to use string.replace() you could do something like this

[shadow pagoda]

i see

is it ever a bad thing to shorten code as much as possible?

[open mural]

nope it isnt

[shadow pagoda]

on codingbat the solutions are always way shorter than mine heh

[open mural]

shorter code == more readable

[open mural]

oh damn

it dosent matter there are 100 solutions for same problem

# with the power of regex
import re
kek = 'smtn'
re.sub('s', '', kek)```

is another method

[shadow pagoda]

cool thx

[elder trail]

The solution has to be readable and efficient, is not a sin to get a larger piece of code as long as itsmore efficient than a shorter piece of code, remember that you have to know why is more efficient (Im struggling in this part)and then youre good to go

[rich canyon]

This is very true. And if the code is very short and not readable it is not manageable. A longer piece of code can be indeed more efficient than a shorter one but the other way around is also possible :).

[shadow pagoda]

so longer code could potentially run faster than shorter or no?

[rich canyon]

No, not in particular. Longer code could be better managable but it all depends on your situation and what you want do to. If your code is working and you can manage it and it relative fast than it is good code (in my opinion, Im not a software engineer 🙂 ).

[lusty bridge]

i feel like, particularly employers, would prefer shorter code if it is just as efficient bc it is better for maintainability and makes it clearer yk (idrk)

[rich canyon]

But then is the question is shorter code clearer and better maintainable (JK)? Everyone has different thoughts about it and it will be a long discussion and you don't get a clear answer 🙂 .

[idle dew]

can anyone help me how to disable slow mode on discord

[karmic cradle]

Can anyone help me setup a virtual machine on my PC? I run windows but my class needs a linux OS ... having tech issues plz help

[elder trail]

have you enabled hyperV?

[karmic cradle]

Yes. installed ubuntu as well ...

[stoic hawk]

have you tried virtualbox?

[karmic cradle]

that's the one I want to try next. can i msg you privately about the steps for this one?

[stoic hawk]

yea

what linux flavor are you searching for?

is it ubuntu/

?

and are you working in windows 10?

@karmic cradle

[regal vale]

anyone know java i can dm?

[coarse river]

@mystic crater Heyy sorry to bother you again but I still have one issue with my program can you help me please?

[mystic crater]

yeah whassup

[spare ocean]

ask here

[coarse river]

ok so I basically fixed but the problem is with the length of logs() it should be 979 but it is only 4 (it is taking the forst dict in consideration only)

import re
def logs():
with open("logdata.txt", "r")as file:
logdata = file.read()
pattern = '''
(?P<host>.[^-])
(\s-\s)
(?P<user_name>-|\w)
(\s[)
(?P<time>.)(?=])
(]\s")
(?P<request>POST.)(?=")
'''
for one_item in re.finditer(pattern, logdata, re.VERBOSE):
return one_item.groupdict()
print(logs())
print(len(logs()))

[mystic crater]

i still dont see you using the correct regex tokens (^$)

[coarse river]

I tried to use it but the document is one full string so it is taking the last element in consideration and returning nothing

[river nexus]

Putting a return statement in a loop means you're only returning the first iteration of that loop. If you want to return all of them, return the iterator itself.

[mystic crater]

true ^^

[river nexus]

I just jumped in without knowing what the problem is. Hope I didn't just throw a misplaced comment 😄

[coarse river]

how do i do that?

i know the problem is with the return bc when I used print it worked fine but I don't know how to fix it

[river nexus]

I don't know much python, but I'd say you should check out the map function

so that you can return the groupdict() of each element

[mystic crater]

you could save them in a list then return it at the end of the function

[coarse river]

I tried that but the assignment requires us to put it in the log itself

[coarse river]

ill check it out thanks

[regal vale]

i managed

had to create an algorithm to print out prime numbers till a certain point but having to call another method that checks if theyre prime

if that makes sense

couldnt get it to work for some dumb reason

turns out i had a for loop with bad condition

[storm marsh]

heyy im a beginner in code but i’d really love to learn coding, which language would you recommend me to study first and do you have any particular tip ?

[spare ocean]

it depends on what you like to do: data science, making a good design / work with UI (front-end) or make the software and hardware part of the service (back-end). personally, I started with Python, but then I fell in love with JavaScript with all my heart.

[sand gate]

if you don't know where to start, python is good because the syntax is very similar to english. My main tip would be to be patient at first because it will be hard until you understand how computer languages work. Once you're past the beginner stage, you can use code to create practically anything and its super fun

Also copy and paste from stack overflow a lot, lol

[idle dew]

I agree with these two. I'd recommend learning the basics of python and if you want to get https://www.makerfabs.com/pewpew-standalone.html this mini handheld console, you can put it into practice in a really fun way. You can make mini games on a grid of 8x8 pixels and once you're familiar with python you'll be able to make anything that ranges from easy to difficult.

[storm marsh]

thanks so much everyone, i’m so glad you helped me, your advices really motivated me !! thks!! 🙂

[spare ocean]

wish you luck!

[elder trail]

guys any good course of DS and algs w implementation (regardless of PL)

[idle dew]

In general, Brilliant offers great courses

[coarse river]

@mystic crater @river nexus
thanks for your help guys. I submited the assignment and got a full grade!

[river nexus]

cool

[mystic crater]

Nice bro congrats

[elder trail]

Guys i need help on implementation of Data structures, does any1 hae a video or a course?

[river nexus]

What kind of data structure?

[elder trail]

the most common ones

https://www.udemy.com/course/datastructurescncpp/ i think ill buy this course

i mean, i can surely find the info of that course on internet for free, but the structure of the course will be better than doing it myself i think

[river nexus]

While this will probably explain the concepts, if you're looking for actual implementations, there's no escaping foraging through github for other people's implementations

[elder trail]

got it, thanks man

[river nexus]

https://github.com/TheAlgorithms Check this out

These are quite good for educational purposes. Most of them are suboptimal implementations that you'd need to fiddle around with for better efficiency, ..etc.

[inner tiger]

Hi can anyone explain why the answer to this would be d and not c

[elder trail]

missing assignment on y++

i think

@river nexus knows better

[river nexus]

In the

public static void increase(int y) {
  y++;
}
```, you pass a normal integer. So when you do ```java
increase(y[0]);

It behaves like ```java
increase(1);

Since the function is passed an integer, it is not aware of the fact that it is an element in an array, it just received a copy of it.

[elder trail]

i was thinking the same, im not that bad after all

[river nexus]

When you pass integers to functions you pass them "by value" which means they are copied. However, for something like arrays, copying them is a headache so they're just kept in place and their address is sent to the function, so when you edit that passed array, changes are made in the original one.

[river nexus]

No reason to think you are 🙂

[elder trail]

I find DS and algs hard enough :c

[river nexus]

Java is just a mess with that pass by value/reference stuff because they're implicit

[river nexus]

Spoiler alert: nobody uses these things

well most of them at least

[elder trail]

Yea but I need them in order to get the Facebook Internship I want

[river nexus]

they're just there for HR to have questions to ask you when you're applying for a job

[elder trail]

T H I S

[inner tiger]

thanks so much for the explanation @river nexus ! So when we are calling increase(1) , y becomes 2 in the array? and now the array for y = {2,2,3,4,5} , however, 1 remains the original primitive value for y[0]?

[river nexus]

Not really. When you call increase(y[0]) the function receives it as increase(1) and thus it has no context of being in an array.

it gets a copy, increments the copy, then the copy is actually discarded when the function returns. So actually nothing is changed

[elder trail]

yea, in the previous one, you can see the reference to the arr position, in increase(y) you pass the element as a parameter and the copy thing that sis mentioned goes on

[inner tiger]

got it, that makes sense, however, the copy is fully discrded? so the result of increase(1) <-- 1 is not stored anywhere?

[river nexus]

yup

[inner tiger]

Thats a lot clearer, tysm! appreciate the detailed response

[elder trail]

Is kinda nnoying that I have to learn this things just to pass de coding interview

[inner tiger]

Will be taking DS and algorithms next semester 😬 how is it?

[river nexus]

Well, in rare occasions, they can prove useful. (but mostly as a reference)

[elder trail]

I'm taking it by myself and at the moment, the abstract/theorical part is easy but I never have seen the implementation so...

[inner tiger]

Nice! what course are you following for it for self-learning?

[elder trail]

Actually, many of it

Im reading Data structures and algorithms in JavaScript (i like the language)

And taking a youtube course of implementation of DS and algs in C++

[inner tiger]

Nice!! I haven't really touched C++ at all and only have a tiny bit of knowledge on JS, my DS and algs class is gonna be in Java from what I see in the syllabus. Good Luck man!

[elder trail]

I'm kinda going hard with it as u can see

[serene oracle]

hey guys, i know python, i want to get into competitive programming but with the language C++, any tips on practice for competitive coding

[vital thicket]

https://www.codingninjas.com/blog/2021/01/09/how-to-get-started-with-competitive-programming/

[serene oracle]

thank you

[inner tiger]

I believe the answer is D, extending the class A (parent class) onto class B (child class) means that class B inherits from A all the methods and instance variables within it. Therefore, although class B COULD use the message method already, the fact that you declare it again within class B means that you are OVERRIDING the method to behave in a different manner than it was declared in class A. Hence when you call line 4, your output would be "B2" instead of "A2"

[little reef]

I originally thought the same as well, however the answer is somehow A

This was the explanation but it made no sense

Also I have been trying to use VS Code but it keeps showing this

It didn't before but after I downloaded Python package it occurred

[timid violet]

le python?

Python est dur

Vous avez un virus de cheval de Troie. Ton ordinateur va se briser

[inner tiger]

OOOOH

@little reef I didn't read the question properly

So basically they are asking what will happen if you remove the message method from class A

[timid violet]

oui

[little reef]

Lmao you know what's sad about this? My AP test be tomorrow 😦

And I can't read problems either

Reminds me when I accidently forgot to finish an entire page of a math test

Three times in a row

So I gave my test to my teacher to make sure I finished

[timid violet]

non

it bad for yu

but can do

if practice

[little reef]

Thanks

[timid violet]

👍

advanced caus yu r tayking hard class

[inner tiger]

Pretty much, the explanation says you will get a compile error because on line 3 when you call obj1.message(3), obj1 is an object of class A even though you instaniate it as a new object of B (because of inherited shared properties).

When you call the .message method on the obj1 it will go to class A to look for the method and execute it. Since the method will not be there if you remove it you get an error, IT DOES NOT suffice to override the method in class B (what is gonna be overriden if its not there to begin with? - ex: how will a child inherit blue eyes from a parent if the parent and their whole family history has only ever had brown eyes? )

LONG STORY SHORT: The child always inherits from the parent, the parent CANNOT inherit from the child EVERRR

[timid violet]

@red kelp BONJOUR, J'AIME STRAWBERRie shorthcaike

Java can be tricky tbh, I am taking it rn college level and it was jump from python bro. I had no previous background in programming before college so definitely good for you to be in AP and starting early, takes a lot of practice and focus time for sure

[little reef]

When discord teaches better than your teacher

Bet thx bro

Np man, best of luck on your exam and lmao mood man, bless the discord people for helping me out as well 🥲

[timid violet]

francais o englesh?

sorry

not spelling good

dont make fun

[timid violet]

why eviryone speak englesh

[red kelp]

because im american

[inner tiger]

yeah I think this server is USA based primarily @timid violet , thats why there may not be many other languages spoken

[timid violet]

ohhh thanks you'

[inner tiger]

You're welcome 🙂

[fluid jewel]

This is international server. Read the #rules before joining any server bruh

[timid violet]

sorry bruh 😆

[little reef]

Last problem

Answer is D don't know how

Also what does static do vs just an int?

[amber nexus]

static means it can be called without an object of the class

you can just do class.(whatever the static thing is)

it also technically makes it so there is only one of that variable since there cant be many of it linked to different objects

but it's not immutable

So basically the answer is d because the variable x is different for each object (first, second, third) but the y variable is the same for each object, so any change that is made to y in each method call changes the y value everywhere. So if you understand that, to get the answer you just follow the program and do the math

[severe spoke]

Y is incremented each time a SomeClass object is created. This is because y is a static variable (belongs to every object in the class). When we call the incrementY function later, the first call increments by one. The second call has a parameter so the second incrementY function is called, which adds 10 to Y. getY returns the static y variable which is 14.

hopefully that helps

[lean gyro]

can someone help me with a cs problem?

this is the question

[inner tiger]

Hi can someone explain how the answer is C please

like how are we getting an ArrayIndexOutOfBoundsException, wouldnt the for loop stop before the program crashes since 5 < 5 would not be true?

[amber nexus]

Yeah you seem right, unless we are both blind, there seems to be no error there... Have you tried running it?

[inner tiger]

''' I

yes I figured it out thank you though

The print statememnt is actually NOT in the for loop

[amber nexus]

lmao

guess we were blind

didnt notice the missing bracket

[pearl cedar]

You can check out the status bar at the bottom to verify that VScode is recognizing the correct language. If it's correct, I guess the squiggly could be due to a VScode linting extension you may have added

Anyways good luck to everyone taking APs. I failed my AP CS exam in high school, but now I'm out here teaching people how to code so it's all gonna turn out fine y'all

[azure pawn]

the statement is out of the loop meaning that the value you're trying to index is some random value of 'int i '

usually it is some weird high value which is obv > 5 in your case

[inner tiger]

haha yes but actually we would not need to put the brackets if the "if" block only has one statement 😮

[digital wadi]

is Hp Envy good for student??

[azure pawn]

which model ?

and it really depends on your needs

[digital wadi]

x13

[azure pawn]

it's decent for office work but for CS i'd recommand xps 13 from dell

[amber nexus]

ya I know 👍🏻 same for all loops

[tacit kite]

that's pure preference. you don't need a specific model for CS. just go with something with decent specs for your needs (usually decent CPU and enough ram, and a decent GPU if you game)

many of my colleges get by with a 100$ thinkpad, for instance

[umbral plume]

does anyone know how james changes between mac and windows on his pc?

[idle dew]

Probably bootcamp

[wheat swallow]

Has anybody experiences with the IntelliJ IDEA for Java? Is it normal for the build to take 5 to 10 seconds even for just a simple "hello World" script? Seems ways to long

[craggy blaze]

that is a while lol

[warped raft]

Can you run linux on macOS if so what’s the best way to get it

Would I need to use bootcamp

[slim chasm]

I need help with adsa

Anyone?

[rustic mesa]

I don't have a mac myself, but in most cases you can do everything in your shell that you can do on linux. Because they are both unix systems
Otherwise get a vm (like vagrant for example)

[idle dew]

Fuck

[amber nexus]

👀

RIP

[idle dew]

Gonna fix it tho

Cant leave it like that

[tacit kite]

Bootcamp if you want dualboot, virtualmachine (runs like an APP) or just run directly on MacOS the commands directly

[modest yoke]

isn't bootcamp to install windows ?

[empty sphinx]

Can someone who knows word pretty well help me?

i have to create a table of contents but some titles don't appear

[idle dew]

That depends on the headings you choose for your titles

Did you update the table?

[empty sphinx]

Do i somehow have to modify the style of these titles to specify to word that they are titles? I can't find that option

[idle dew]

I often forget

[empty sphinx]

I'm not sure i know how to do that haha...

[idle dew]

Haha one sec

In the home tab, you can select styles and format the text with that

[neat viper]

Any machine learning experts here? Can someone help me understanding Test-Time Augumentation. And is it possible to apply this to the validation set or is it only for the test set?

[idle dew]

If you choose one of the headings, it will show up in your table of contents @empty sphinx

Once you select Heading 2, the option for 3 will show up and then 4 will show up etc...

[empty sphinx]

the thing is i have to use a specific style for this, and i think it isn't considered a heading @idle dew

[idle dew]

Ah

Hmmmm

Lemme think

Worst case you can add it to the TOC yourself at the end

[empty sphinx]

hahaha i won't get the points for the TOC tho

[idle dew]

It has to be clickable and then send you to the page?

[empty sphinx]

yup...

[idle dew]

One sec, lemme record it for you

There's another way

When it asks you to replace the TOC, say yes

I hope that does it for you. You can select the level of indentation for each of the styles

It's a bit convoluted, but I think this is what you need

@empty sphinx

[empty sphinx]

Oh yeeeessss i think that's exactly what i was looking for!!! Thank you so much for your time!

[idle dew]

You are very welcome! Good luck with your assignment! 💪

[empty sphinx]

Thanks! Good luck with your work too 🙂

[idle dew]

Thank you!

[hushed needle]

does anyone know how i should go about this? I don't how to get rid of the application because this message keeps popping up.

[grim vale]

For the JavaScript smart people, if I have a function with a setTimeout, if I want to repeat this function n times, but want to wait for it to finish before repeating it, should I wrap the function call in a setInterval or is there a smarter way to do it?

so long as the function finishes completely before repeating is really what I'm concerned about, rather than just repeating it twice every time it's called

[spare ocean]

Did you try to write a promise?

[grim vale]

I did not because I haven't googled what that is, yet

[spare ocean]

so you can try to do a setInterval, if will not work, maybe a promise, be sure that u cant put setTimeout inside another timeout cause its all async functions

[grim vale]

yeah to give you some context

I'm writing a function that if you do
!study number, you gain the study role for that amount of sessions

currently the sessions are set to 5 seconds because I'm not spending too much time waiting for a function to run, so 5 seconds is a nice amount of waiting

then it gives you the Break role, after the study part is done

however, if I want to do !study 2, it just calls the function twice instantly, where I want it to wait until study session 1 is done before doing study session 2

[spare ocean]

Is it discord bot?

[grim vale]

I was going to do like
let currentSession = 0;
for (i = 0; i < currentSession; i++) {
function here
currentSession++
}

yeah

that was one way I was gonna do, but I figured that way is kinda, dumb?

[spare ocean]

It can simply add the user's ID to the "session" and check if the same user creates a session, give him an error, because the last one is not finished?

[grim vale]

oh

if you have the study role

it removes all ability to speak

[spare ocean]

[grim vale]

you can only react to force end a session

it's to incentive people not procrastinating

If you do the !study command, it forces you into a position where you can't be distracted

eventually I'll learn how databases work and make a leaderboard

[spare ocean]

maybe then some object Date, which will be removed from the array of sessions?

[grim vale]

since people enjoy seeing themselves as #1, which would incentive people further

[spare ocean]

I think it is clearly necessary to use the library for date or the built-in Date() than interval, at least because of the semantics of the code

[grim vale]

yeah so far, I've enjoyed writing my own code since I'm using discord bots as a teaching myself how to code excercise

but if I should just, resort to libraries to make life easier then why not

[spare ocean]

Date() built in JS, it's also good, just libraries are even easier

[grim vale]

so if I'm understanding this correctly, or if my thought process is correct

if I change the session to be one minute for simplicity

Date() has a time in it, so if I check that & it's 17:30:00
!study 1 = 1 minute of study, 30 seconds of break
if time =17:31:00, remove study & apply break
if time = 17:31:30, remove break, apply study if studySession < 1 & repeat

ok so it looks like

a server I'm in uses and as emotes

[spare ocean]

in any case, it's worth a try)

[grim vale]

yeah I had to do 17:31:00

because if I do : 31 :

it's an emote

[spare ocean]

[grim vale]

idk

Hi

[idle dew]

how much JS do I need to start learning Angular or Reactjs ?

[azure pawn]

that's relative but imho : Once you feel comfortable with basics of : DOM manipulation and AJAX and how you deal with different librarieries in the same proj

[idle dew]

oh it must be a long road then 😅

[azure pawn]

depends on how much effort you put into it , if you're aiming for a full stack js dev you'd take a year to be market ready usually (average(

some people learn faster so yh it depends

[idle dew]

I do learn fast, but I dont know how to practice and on what

[azure pawn]

i'd say project based learning is your best friend

Clone websites if you don't have ideas for ones

[sleek wyvern]

ill pin it here for now! thanks!

[blissful musk]

what do you do for work? I'm a react dev

[idle dew]

also a react dev, but mostly front-end so I may very on the tech. I currently worked on Nextjs and Flutter mobile projects

[blissful musk]

its insane how popular nextjs got so quickly

I work on a pretty standard react/graphql codebase and we can dip into the backend if we're familiar with the feature

[ivory crystal]

Y

[idle dew]

same thing exactly

using wordpress graphql as back end

next on the frontend layer

they assign me to the whole project so I need to study 12 hour straight lol

[blissful musk]

lol jesus, dude wordpress backend is a nightmare depending on what you're doing. My first paid job ever I had to migrate a database to wordpress and it was ridiculous. Maybe its changed since then 😆

Next sounds cool though and Graphql is so much easier than REST

more config though

[idle dew]

naah its still a hell lol

[blissful musk]

Is the db set up the same way where like basically everything in the entire site is basically on 1 table with the columns

3 columns*

it was like [id, key, value] that was the schema for the table that all of the content on your entire site went in lol

[idle dew]

I'm learning dev and my first try on a project? a damn pern stack

i got the backend connected easy and its simple but react is blowing my brains out

[idle dew]

Anyone here Animation artist
I need to make a 3 minutes film
Can anyone help me out

I will pay for it accordingly

Dm me

[pseudo ridge]

some1 pls tell what wrong here, ping me

[rancid tide]

iirc strings are immutable

instead of trying to edit the input string and then append it, try using sampstr += sampStr[i].upper()/lower etc

Can't say I've ever really used python before, but this worked

would pomodoro method work with learning python? or is it just really the method i prefer to learn with?

[grim vale]

100% how you learn best

Pomodoro is good for building habits for studying

Not actually studying itself

What you do in that hour is how you'll retain the information, pomodoro just helps you build the habit and groove of setting aside time to study

For me personally, with JavaScript, I make Discord Bots, it's how I've been teaching myself JavaScript, I don't particular do the pomodoro method when making them since I tend to have spontaneous bursts of energy as opposed to consistent effort

[thorn lantern]

There is a new rule (rule number 5), please read it before using the help channels! #welcome-verification

[hot anvil]

This code ought to crypt the messege with polish sugns

but it does not

[azure pawn]

what output do you get ?

[grim vale]

just as a preference, at the very top of your code block, beside the 3 backticks, can you put "cp" there?

also yes, as Good mentioned, what is your output (and expected output)

[humble seal]

Its Cesar Code, for example I want word "Słoń" encrypted into "Vorq"

It moves 3 letters

sry i'm not a native

thats the output I get so not even close

[humble seal]

whats cp?

[grim vale]

c plus

it introduces syntax highlighting

#include <iostream>
#include <fstream>

using namespace std;

const string alfabetmala="aąbcćdeęfghijklłmnńoópqrsśtuvwxyzźż";
const string alfabetduza="AĄBCĆDEĘFGHIJKLŁMNŃOÓPQRSŚTUVWYZŹŻ";

my mistake, it's c++ not cp

if you add that beside your back ticks, it highlights stuff making it easier to read

[humble seal]

done, thx I didn't know that

So could you help me? xd

[grim vale]

I'm cooking food atm, but I'll check it out after

[azure pawn]

@humble seal what is the expected output tho ?

hmm you forgot an X in your alphabet

[humble seal]

hmm good point

[azure pawn]

and why is why
i=(i+klucz)%35; but then kod=kod-26;
seems like a mismatch in constants

[azure pawn]

not me but i reached for someone

And btw All Polish letters are greater than 'z' in terms of ASCII

so you must change the encoding

that causes conflicts

[humble seal]

even after changing it

it still cause trouble

[azure pawn]

try it with English Alphabet

i don't c any obvious errors on the code

[humble seal]

With English Alphabet it works fine

But i need it with the Polish one : P

[open mural]

my program is being killed by os its being killed because its using all the memory could anyone help me debug this memory error it is supposed to read a csv file and put that data into a linked list

[river nexus]

You're mallocing in a loop with no frees

There could probably be some weird logic in the loops but tbh this indentation is a pain to read

[azure pawn]

been looking for the code like something is missing just to realise the (25 lines left xD)

[open mural]

XD im new to c/cpp

[rugged relic]

hi guys, is someone good with python? i need to modify this program a little and i don't know how.

1. if someone enters wrong amount a massage "you entered wrong amount" must pop up and the program has to be killed
2. if someone enters wrong payment a massage "you entered wrong payment" must pop up and the program has to be killed
   i would be really grateful if somebody would help me understand this, because i'm not that good with python yet

[azure pawn]

i'd say redesign your algorithme and as sisyphus said use free

[open mural]

thanks btw

[open mural]

ye thank you i will try that

[azure pawn]

can you copy&paste and format the code here

[rugged relic]

amount = float(input("Type in required amount: "))
sum_payments = 0

while sum_payments < amount:
payment = float(input("Type in your payment: "))
sum_payments = sum_payments + payment
print("Current sum of payments is: ", sum_payments)

overpayment = sum_payments - amount

print("Overpayment is: ", overpayment)
print("Sum of payments is: ", sum_payments)

[river nexus]

amount = float(input("Type in required amount: "))
sum_payments = 0

while sum_payments < amount:
    payment = float(input("Type in your payment: "))
    sum_payments = sum_payments + payment
    print("Current sum of payments is:  ", sum_payments)

overpayment = sum_payments - amount

print("Overpayment is: ", overpayment)
print("Sum of payments is: ", sum_payments)

wrapping in 3 backticks helps with code formatting

[rugged relic]

oh thanks, i didn't know

[azure pawn]

first thing you didn't declare amount ^

so the while loop doesn't really make sense to exit

[river nexus]

Not a python user but AFAIK you don't need to declare, you just define and use as if it was there all along XD

[rugged relic]

yeah it's a program i had to prescribe from my teacher, so i did and don't know what to do with this

[azure pawn]

i m referencing to the logic operation

sum < amount

sum is initialized to 0

amount should also be initialised

that's the first glance at the problem

[humble seal]

doesnt change a thing unfortunetely

[river nexus]

amount is initialized to input() in the first line

[azure pawn]

ooh didn't c that my fault

copy pasted without the first line xD

[river nexus]

I'm assuming "wrong amount/payment" you mentioned here means invalid?

[rugged relic]

yes

[river nexus]

https://www.geeksforgeeks.org/float-in-python/#:~:text=The float() method is,a number or a string.&text=The method only accepts one,or a floating point number.

[rugged relic]

i assume that it has to work if someone puts 0 as amount or payment, but i'm not sure, my teacher didn't specify it

[river nexus]

did you ever deal with exceptions in any programming language?

[rugged relic]

yes i did, but they were a lot easier

[river nexus]

https://www.w3schools.com/python/python_try_except.asp well python has a try/except pair and float raises an exception whenever an invalid string is passed

[rugged relic]

okay, i'll try to use it, thanks

[river nexus]

keep in mind that this will only handle invalid floats. so if you want to, for example, reject negative numbers, you'll need to check it yourself

[hot anvil]

@azure pawn did you study the coursera google data analysis course??

[gleaming dragon]

Whats a good way to start coding for a begginer?

[grim vale]

check pins friendo

[gleaming dragon]

Sweet thnx

What could be a good language to start with? I started Python in college but didn't finish it.

[idle dew]

I've heard Java is a great place to start

[wooden heart]

hey i am using discord on arch linux, and when i am sharing screen , the options of sharing other applications is not coming any solutions

[wheat swallow]

what do you wanna do with it?

[gleaming dragon]

Alright I opened a bunch of tabs and 1 tab is for CodeWars, though it says start with Kyu8 for absolute beginners, to sign up it already gives me a code to begin with! It says it doesnt execute properly but I don't know how to execute it properly???

[gleaming dragon]

What do you mean?

[grim vale]

well code is quite broad

[wheat swallow]

do you wanna make games, websites, analyze data etc.

[gleaming dragon]

I guess games would be good for me.

[grim vale]

do you have a link as to what one you were looking at?

[gleaming dragon]

https://www.codewars.com/

I started that 1, I click to sign up. Choose Java, and bam a whole code that doesnt execute properly...

[wheat swallow]

hm c++ is the one used mostly for games, but it's not at as easy to learn as others. I would recommend python or java. and if you like it you can still switch to c++ later on for game development

[grim vale]

If they're looking for game dev

C# probably isn't a bad place

allows them to dip into unity quite freely

ok so @gleaming dragon

that very first one

just click submit

If you have a problem where code doesn't run correctly, or compile

compile it anyway & see what the error is

the error will tell you what the problem is

[grim vale]

yep

what does the error tell you?

[gleaming dragon]

If I were to take a wild guess

It says ";"

So delete that and it works?

[grim vale]

Delete what?

[gleaming dragon]

no add!

[grim vale]

"error: ';' expected
return a * b
^

So, where the arrow points is where the error lies

If it expects a ; to be there

why not try adding one & hit submit again

[gleaming dragon]

I just did, and it worked

[grim vale]

[gleaming dragon]

Though there was no arrow..?

It was just plain

[grim vale]

There is an arrow

[hot anvil]

for me C is the best for beginners first they will learn all the fundamentals such as pointers piles files

[grim vale]

yeah, but for someone who doesn't understand syntax or logic flow or anything of the sort

Getting them to start with C, and having to deal with manual memory alloc in alot of exercises

probably isn't the best course of action

[hot anvil]

but with that they will learn all theoretical and practical things

[grim vale]

yaeh

[hot anvil]

plus of they want to switch to any language i don't think they will have problem with that

[grim vale]

I think C# is probably a pretty good place to start, for someone who wants to do game dev

[hot anvil]

c# gives many possibilities it's also good for desktop windows apps dev

[wheat swallow]

i feel like to much theory is bad for beginners, some people just want to learn to code and not learn CS

[grim vale]

C++ definitely is a good language to learn

just not a good one to learn first

[gleaming dragon]

Isn't Coding CS?

[wheat swallow]

yeah and no, there is a lot of theory behind CS that you don't need to know imo

if you start out at least

[hot anvil]

in my opinion you will learn theorical parts sooner or later while you're coding

[hot anvil]

that's true but there's some basics you just can't ignore

i have a cs degree and it's really helping me like recently i learnt python and i didn't have much problem with cause earlier like i knew what's high lvl language and what's lower lvl language or how it's compiled and stuff

[grim vale]

ok but

[wheat swallow]

nobody denies that it helps a lot. The question is if it is the best way to start out.

[grim vale]

they don't have a cs degree

[hot anvil]

yh my point is that beginners should at least get the basics of theoretical stuff bcz that's gonna make learning the language much easier

[wheat swallow]

There is a huge difference if you enrol in a CS degree or just want to start out and test the waters. If you are not sure if you like coding, starting with C or too much theory can be frustrating and boring and turn people away

[hot anvil]

yeah that's for sure

[gleaming dragon]

Says choose the languages I wish to train on, basically just I can choose multiple. is it best to pick a few or just 1?

[hot anvil]

i think the best thing is to choose one on the field that you wanna work and stick to 1 langauge to master it

[pearl cedar]

I learned python, R, java, C++ in that order and over multiple years. I work with data science now and I mainly use python but knowing java helps. I don't think it really mattered where I started - the important thing is to just start!

[grim roost]

does anyone know how it is possible to do a data transfer from a machine on a network to a private server via vpn and firewall?

distributed systems and cloud computing can be a solution?

[hot anvil]

@pearl cedar i'm studying data science may i ask you some question in dms?

[unborn talon]

use an ssh tunnel

[pearl cedar]

I am only grad student tho but sure!

[grim roost]

thanks, I appreciate

[unborn talon]

im not sure if that was descriptive enough to be helpful, but if you use rsync/sftp/scp or something you should be able to get it across.

[grim roost]

no problem, I needed some inspiration I'm doing an elaborate

[boreal magnet]

Start with C++ in my opinion. It'll help you understand more about programming concepts. Also then you'll be able to switch between languages in a week at max.

Hackerrank has language proficiency problems which i find useful

[azure pawn]

on my schedule for this summer

[hot anvil]

what's your niche ? are you into data science?

[azure pawn]

thinking about switching to big data/data analysis next year

college here is different , i studied 1 year of "pure CS" , now i get to choose whatever field want to continue in (SE, data analysis , Multimedia and design , Web Dev ,IOT etc )

[hot anvil]

oh okey

[stuck crypt]

Hello guys, I need help in a school work involving clustering. Does anybody here knows some methods used in clustering?

[hallow mist]

using deep learning or more statistical methods such as kmeans, etc.?

[hot anvil]

i know kmeans(the theoretical part)

[stuck crypt]

The course bioinformatics, so I was wondering how could i relate clustering with biology

[hallow mist]

your gonna need someone that specializes more in biology than ml probably, but thats coming from someone who knows nothing about biology

[stuck crypt]

ok thanks anyways

[hallow mist]

this is what a quick google search brings up if it means anything

[main acorn]

@hallow mist do u have the link for that?

[hallow mist]

not sure I can paste links but if you want I can dm it to you

[main acorn]

yes pls

Data analysis / ML-DL is becoming huge. It's definitely the future

[azure pawn]

[tacit kite]

Best of luck! I'm in that road myself too.

[azure pawn]

i'll enroll google data cert this weekend most likely

i mean it is in R (meanwhile IBM's is in python) but i guess it's about the logic 🤷‍♂️

how about you where you planning to start ?

[wheat swallow]

Can you talk a bit about it? Isn't just a test you do only ?

[grim roost]

thanks mate!

[tacit kite]

Both are great for ML/DL. Pick one you like, cant go wrong either way

Btw, MIT has a paid online course in ML with certification. Not cheap (around 2k) but content is good and most importantly you get MIT certified

[azure pawn]

no , it's a full course you can check the summery in coursera basically by the end of the course you'll have the foundation to search for an internship as a data analyst in other words you're supposed to be market ready (you;ll learn data cleaning , data visualisation etc , R programming )

[azure pawn]

it is worth the money tho , a college/uni name is an important factor for getting some good internships

[modest wolf]

anyone understand this psuedocode smh. if given the array 3,2,5,4,1 whats the output be, i got the answer but the psuedocode seems vauge

[hot anvil]

I didn’t understand it but if u want a algo that sort data which is table i can help you

[tranquil pagoda]

this is bubble sort right?

[unborn talon]

wait what, is consider every ith value of data starting at data[1] meant to be a second for loop

[mystic crater]

i think it just puts the biggest value in the array at the end so basically only the first iteration of bubble sort

[unborn talon]

for i = n-1; i > 0; i-- {
 // consider every ith value of data from data[1]
  for j = 1; j < n; j++ {
    if data[i] < data[j] {
      swap data[i] and data[j]
     }
   }
}

[hot anvil]

that's the right answer it has to be 2 loops

[mystic crater]

makes more sense tbh

[tranquil pagoda]

this makes sense

[mystic crater]

actually if it was bubble sort they wouldve put two loops since they already used one so ig it just puts the max at the end

[hot anvil]

but if with one loop doesn't sort all the data

as you said it would do just the first step of sorting

[unborn talon]

if you could sort in n, wouldnt you get an award

[hot anvil]

the best sort algorithm by it's complexity it's the merge sort

[unborn talon]

good point

[hot anvil]

it's as i remember O(n)=nlog(n)

[tacit kite]

Is it good and worth- yes
Is it enough - maube not. You probably want to have a foundation of some sort. Something like an engineer degree (EE, CE, whatever fits your goals) will cover your bases.
At least here, many companies care more about differentiating factors, and an MIT formation is a big one.

Not sure about that google course tho

[modest wolf]

idk but this just a algo prof gave us to prove its correctness; but the psuedocode seems vague

im learning algo analysis

heres the step not look like the psuedocode she gave

maybe the slides got problem she not that organize lolll

[modest wolf]

felt so dumb learning analysis kekw

why at k+1 iteration it swap min of range [k+1, n] to data[k] but not data[k+1]
the pseudocode said at i would swap min of [i,n] with i
