Hello @somber heath !

would you be able to help me out
with something
How would you be able to replicate a website like: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-javascript/assigning-the-value-of-one-variable-to-another
but with python
vocal basin
the test system?
vocal basin
how much do you trust the users?
boreal abyss
how much do you trust the users?
not at all
vocal basin
as for isolation, there exist per-language sandboxes and some generic ones
generic approach normally involves containerisation of some sort
I'd expect namespaces/cgroups or its derivatives (including Docker) to be used there
boreal abyss
the sandboxing itself is just docker no?
vocal basin
just a message broker

I have experience with SQL but not much
I prefer using ORMs or simpler data storage mechanisms
tulip plover
if a have a sql table from one of the items i get the rowid how can I get that same rowid in a other table
vocal basin
rowids across tables aren't correlated, usually
FK from one table's column to another's rowid column could be a thing
i.e. enforcing that referencing table's rows are each associated to at most one row in referenced table
vocal basin

how are the two tables related?
tulip plover
I have 2 table one of the table have the users login the other one have some information's on the account how can I connect them

@vocal basin suppose I am the only user

how would I go about recreating something like freecodecamp, but for python input/output?
I've had several ideas
but none of them are elegant

I think that's, like, only part of what disallows it
the real general reason is:
current user lacks the privileges
within the container even
assuming code isn't ran as root
basic logic of a runner could be:
clear everything that a sandboxed program can read/write
receive next request
run the code as a restricted user
either wait for the completion or kill on timeout
gather results, send somewhere else
repeat
stopping certain programs could be difficult

Right now the way my program works is you type in a bunch of commands. The way it does that right now is by having one function manage running all of that with the exception of looping. To make it worse in the one function there is just a whole lot of elifs. Right now this is the best I have because I started this project when I was very new to python. I have tried to simplify code but there is just soo much.

@toxic arch I've had a tinker with tkinter. Following an example from elsewhere which ought to work...doesn't. I packed and I mainlooped and it doesn't want to display. Tkinter isn't something I'm particularly good at, but I am a little perplexed.
I know I've got image stuff to show up in tkinter, before, so I'm buggered if I know why it's being stupid.

Chatgpt is a good place to study
The problem with that is that it likes to hallucinate sometimes and you pretty much need to fact check everything it tells you and make sure it is still the current way to do things

wind raptor
If you need a second source for info on something, or review on something you kind-of know already, I'd use it
I prefer Udemy 40+ hour well-structured courses. I learn best by watching good videos and following along / deviating from them.

if you are over 5 years old I use IF but if you are less than 5 I use ELSE

What is the difference between else and elif
scarlet halo
What is the difference between else and elif
else doesnt have support for expressions. elif is like a second if statement if the first (or before) fails.
whole bear
age = 7
if age < 5:
print("You're too small!")
else:
print("You're all grown up!!")
In this code you could also use elif instead of else

age = 18
if age > 5:

I didnt understand srry
scarlet halo
I didnt understand srry
its fine that was just a stupid example thingy
basically elif only runs if the previous if statement is False
and else cant have expressions
like you cant do: else x == y: but youll have to do elif x == y:
whole bear
So if the if ago is false, use if elif for true
whole bear
Okay this time I realized
scarlet halo
so if ... elif(s) ... else (optional)
whole bear
If the IF command is false, the next true and elif
scarlet halo
if the if is true no elifs will run either
whole bear
If IF is true the next and else?
scarlet halo
no if if is true no other elifs or elses will be run
whole bear
If IF true I don't need to add any of them
scarlet halo
elses and elifs are good to have incase your if is false
whole bear
Age = 20
if age < 19:
print("ok")
else:
print("okkk")
In this code I use elif
sure?
scarlet halo
no that should be else
theres no expression
in the elif
so its useless
should be else
elif 1==1:
else:
see?
whole bear
Why should it be else and not elif
scarlet halo
your elif doesnt have an expression/condition
therefore it doesnt know whether to run or not
and it gets confused
and might throw an error
whole bear
Can you give an example of each
Age = 20
if age < 19:
print("ok")
else:
print("okkk")
Age = 18
if age < 19:
print("ok")
elif:
print("okkk")
Sure?
scarlet halo
if 1==2:
quit(1) #doesnt execute as 1 is not equal to 2
else:
quit(0) #runs because previous if is false
if 1==2:
pass
elif 1==3:
pass
elif 1==1:
print("success")
If false and elif false but last elif true
scarlet halo
as i said there can also be an "else:" after the last elif
scarlet halo
If false and elif false but last elif true
correct
whole bear
If the first if is false I use elif false and dps a correct?
scarlet halo
you should try reading some more about if statements as theyre pretty similar for each programming language.

Can someone explain to me what a function is
hardy viper
Can someone explain to me what a function is
a function is basically
something that you make to use a certain chunk of code over and over again throughout the code
usually used for big projects
gusty kindle
def myFunction(): [your code]
then you call the code by myFunction
a function can have parameters, like this:
def myFunction(param): [tab]x = param * 2 return x
then you would call it like myFunction(2) and it will return 4

just ASGI + uvicorn
whatever the regular uwsgi does -- likely involves multiple workers too
for IO-bound task, ASGI will be better for most, if concurrency is the issue (as compared to WSGI)

offload to a separate worker process, connect them via a message queue

it is the best way to learn something. Just not the fastest or easiest

Actually I'm wrestling with the temptation to build certain things just to understand them..
Studying code would be great if there were better tools to annotate code and to study code.
We definitely don't have enough of those
lavish rover
what spider said
it's not the most efficient if your goal is to just get a high level understanding
vocal basin
there isn't "the best" way at all, but usually making something yourself improves knowledge compared to not making

or even useful for most things
wise loom
@vocal basin I would rather find a good explanation of something instead of building it myself.
lavish rover
A good explanation will almost never give you a taste for all the actual real technical issues
it tells you what is being done, very rarely why it is, or why it is not done other ways
vocal basin
use the thing => learn what it needs to do (and what you'd need to do if you were to create it)
build the thing => learn how what the implementation challenges are
study your and other's implementation => learn how it affects the use and design

@cosmic bison what's your test-coverage ?
@cosmic bison I was expecting a percentage but okay
lavish rover
But also - there's a personal factor. I really enjoy the process of figuring out how to implement things - not just knowing how they work
it makes me understand the nuances and complexities of the issues, and why people might decide to do it a certain way
wise loom
for @cosmic bison it would be great to not take anything for granted, challenge all possible assumptions, write tests for them and eventually you should find the issue
vocal basin
it tells you what is being done, very rarely _why_ it is, or why it is not done ...
yeah, that's why prefer the thing (which I most often see with Rust) where whoever presenting the design also includes previous (simpler/move naïve) versions and why they were rejected;
Rust "Book"s do this, Steve Klabnik's talks on async have that

@lavish rover what's your test coverage? for the ocen language

measured in what?
percentage basically
wise loom
percentage of what?
of the grammar, like how much of the grammar is hit by the tests
vocal basin
so, basically "lines"
wise loom
let's say yes?
lavish rover
I don't track it, I don't think that's really a meaningful statistic IMO
vocal basin
yeah, statement/expression/line coverage, even if too basic, is still useful
lavish rover
I also don't really have tooling to track it if I wanted to, considering my language is implemented in itself
wise loom
I don't track it, I don't think that's really a meaningful statistic IMO
it kindof is because anything that's not covered by tests is UB(undefined behavior).
that's probably why C++ has so much UB, but also because it's a very complex language..
vocal basin
yeah, statement/expression/line coverage, even if too basic, is still useful
especially when it's <100%
not necessarily UB
it's defined, just not in tests
and some things are inherently untestable
wise loom
and some things are inherently untestable
such as?
vocal basin
IO isn't UB; UB, as a term, applies more to "you failed and the system is free to do whatever it wants"
vocal basin
such as?
any interactions with external systems
"you can't unit-test IO" is basic level for issue;
many aspects (mostly, ones that anyone actually cares about) of a system require testing in a larger setting;
some IO can be tested by increasing the scope that you're dealing with (from unit to integration) but that also decreases the control;
wise loom
still IO test generation is performed using fuzzers

A function is a kind of object which can be considered as being a collection of code. A function can be called upon to be run when required. Here is an example.
!e ```py
def func(): # This is where we say this function is referred to by the variable, func
print('Hello.')
print('Goodbye.')
func() # This is a "call". It causes the function to run.
func()
func()```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | Hello.
002 | Goodbye.
003 | Hello.
004 | Goodbye.
005 | Hello.
006 | Goodbye.
A function also has an "inbox" and a few different, but one main "outbox".
whole bear
def function() :
print ("hey ")
print("hey world")
function()
function()

gentle flint
whole bear
He'll send Hey and Hey World 3 times
somber heath
!e ```py
def func(parameter):
print(parameter)
argument = 'Hello.'
func(argument)```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
Hello.
What's that inside Parameter
somber heath
A function can have parameters. These parameters are variables. The variables are assigned to the objects given in the call. The objects given in the call are called arguments.
Here, I call func. The argument, a string, 'Hello.', has parameter assigned to it within the function.
whole bear
I'm going to try to make something that has a function
somber heath
For later reading: The LEGB rule. Write it down.
Functions also have, as mentioned, an outbox.
!e ```py
def func():
return 123
print(func())```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
123
The object given to return, here 123, replaces the call to the function.
The call becomes/evaluates/transforms into the object returned.
The function still runs, but when it hits return, the object is passed out of the function and into where the call is.
When you hit return, the function terminates.
!e ```py
def func():
print('A')
return
print('B')
func()
func()```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | A
002 | A
All functions that complete, return.
If nothing is explicitly given to be returned, the object None is returned.
!e ```py
def a():
'Code goes here blah blah.'
def b():
return
print(a())
print(b())```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | None
002 | None
We see this in some other calls we can make, to print, for example.
!e py print_return = print('Hello.') print(print_return)
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | Hello.
002 | None
We just don't usually assign variables to such function calls/their return.
Functions can also have more than one parameter. It can get complicated.
!e ```py
def add(a, b):
return a + b
print(add(5, 2))
print(add(50, 2))```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | 7
002 | 52
Arguments and parameters are both separated by commas.
Though you can nest other structures that do have commas.
!e ```py
def func(a, b):
print(a)
print(b)
func((1, 2), 3)```
wise cargoBOT
@somber heath :white_check_mark: Your 3.12 eval job has completed with return code 0.
001 | (1, 2)
002 | 3
I still have two arguments, it's just that the first one is a tuple.

you have to decide that first. Is it a terminal app or GUI app? What will it do? etc.
whole bear
What's the difference
cosmic bison
Terminal app is just text in the console. So basically just uses print and input
GUI is what most apps you use have. GUI is a Graphical User Interface. So it has buttons, text, tabs, headers, images, sliders, etc.
GUI is a lot more difficult. But python does have the Tkinter module for making very basic GUI's
whole bear
Which one do you recommend
cosmic bison
how long have you been writting code?
and what level experience would you rate yourself? beginner, noob, novice, intermediate, advanced?
whole bear
Short time
cosmic bison
okay. I would recommend making simple terminal apps then
whole bear
beginner or noob
cosmic bison
after a few simple projects, you should take a look at tkinter for basic UI
when you get comfortable doing both, then just research whatever you want from there
you could lookup how to make discord bots, website backends (using django), more complex UI with pyQT/pyside, More complex terminal apps using curses, sockets, or anything else that interests you
learning a bit of pygame is a good way to start learning more stuff while still keeping it basic. But do that once you feel comfortable making a few basic tkinter apps on your own.
