I did a Kata last night. Worked, and it needed to not time out on very large input lists, but it was like 30 lines and sorta kludgy. But I got to look at the solutions after...
the right way to do it is 5 short beautiful lines
versed saffron
'right way'
What I've found with the site is if you want to golf your answer you can
But as long as it functions you've solved it
rough sapphire
which kata?
heavy jackal
Yeah, I think that it's meant to work like that. A kata is meant to be something that you basically achieve the form and then you iteratively improve upon it to become more efficient. But cramming my solution down into fewer lines wouldn't have helped because I was approaching the problem backward
or rather
the correct way is to do it backwards.
quick ledge
ah
frozen thorn
Do I need to be good at algs?
versed saffron
Imo i don't find it helps me much but I think people that learn with tutorial/videos should do it. It's super useful to find use cases for different funcs/etc
Nope the basic ones are pretty basic
It's more about understanding the logic
frozen thorn
i think my problem to solve kata is that I often look it up. Like formula or smth. is that bad?
heavy jackal
If you're good at recognising the form of problem you're looking at and research how to solve that problem correctly... I think that's more of a critical skill rather than cheating
frozen thorn
Yeah that's what I mean I guess
heavy jackal
otherwise you need to basically be able to rederive obscure branches of math to solve some problems and that's just doing things the hard way
versed saffron
It's important to understand how each part of the algo/formula works and what it does tho
frozen thorn
Ya
heavy jackal
Oh, yeah, ideally you should understand what you're implementing
frozen thorn
I'm good at math, but still need practice to implement it in code
heavy jackal
but if you need to look at an example to learn then might as well do that
versed saffron
If you just find an answer and copy it, you might know how to solve that specific problem but you're not learning anything
heavy jackal
I find for myself I really have a hard time learning anything without a complete example
versed saffron
That comes with experience but like most of the super simple katas don't require much technical skill they're more for teaching you how to approach more logical based problems
Altho technical skill/knowing how and when to golf can be useful too
frozen thorn
tbh when are solving algs useful for?
Like I don't think you need them in real projects
not at that level
rough sapphire
I think a fresh CS student should start with Algorithms and Data-Structures and most of them won't occur in day to day life. They have importance in interviews so
versed saffron
They're usually applicable in one way or another
That's one thing I've been disliking about uni
If I wasn't learning on the side I think I wouldn't be able to function once if I graduate
frozen thorn
I think same thing if you are only good at solving algs, but never did projects or smth
rough sapphire
Yeah this is the reason why I got out of Algorithm and DS, started learning new things
versed saffron
Well ya even if you have a project that uses a specific algo, it's not going to be the whole project
rough sapphire
and I am enjoying it more than practicing whole day
frozen thorn
Yeah that's why I try to learn from doing projects than kata daily
versed saffron
I like doing Kata if I'm bored
frozen thorn
but I'll get back to codewars again lol. For interview I guess
versed saffron
Then again I like puzzles
rough sapphire
leetcode is better
heavy jackal
I find the katas good because I have some kind of problem thinking up good projects to tackle that are within grasp of my current level
versed saffron
I find I occasionally get inspiration for ways to solve a specific issue I've got too
heavy jackal
Am I meant to be solving these in, like, 30 minutes? I always feel like I need at least an hour
frozen thorn
Probably with experience
versed saffron
Na I think the longest I've spent on one was like 3hrs

versed saffron
im so confused this is worded so poorly
"Given an array of numbers and an index, return the index of the least number larger than the element at the given index, or -1 if there is no such index ( or, where applicable, Nothing or a similarly empty value )."```I was thinking that meant the value with the smallest difference
apparently not
frozen thorn
huh
versed saffron
like with that logic the second one should be 5
heavy jackal
Yeah no, I get it, it is worded kinda strangely
versed saffron
I actually don't know what it's asking
heavy jackal
First example: it gives you index 0. That value is 4. You need to find the smallest number in the list that is bigger than 4 and give that number's index
frozen thorn
yeah i would think that shold be 5
versed saffron
also the fact that -1 is acceptable as an invalid index pisses me off
heavy jackal
Yeah it should be None in my opinion
heavy jackal
I mean, I'm grappling with a cipher problem now and it's got multiple layers including dividing the message into 5 parts, but the rules for dividing up the message doesn't work if your message is 11 characters long
I'm just hoping that never comes up.

heavy jackal
Haaaaaa
frozen thorn
I'm kinda confused. smallest number in the list that is bigger than 4?
quick ledge
b r u h
heavy jackal
versed saffron
ya the smallest difference between numbers bigger than the number at the index and the number at the index
not the least number larger than the element at the given index
the least number
heavy jackal
trying to code shouldn't feel so much like having a stroke
versed saffron
you'd think
frozen thorn

quick ledge
hmm, i can think of a cheaty solution
versed saffron
I did it in 3 lines im so proud of myself
versed saffron
na it's not
def least_larger(a, i):
ind, lst = a[i], []
[lst.append(item) for item in a if item > ind]
return a.index(min(lst)) if len(lst) > 0 else -1```oh dang I could've done it in 1
quick ledge
The solution i have in my mind is definitely cheating
versed saffron
def least_larger(a, i):
return min(((n, c) for c, n in enumerate(a) if n > a[i]), default=(0,-1))[1]```what did you have in mind
heavy jackal
JEEZ. That one certainly dragged out longer than I would have liked. I feel like that one really had too many steps to be considered a kata...
Encode message, attach key, cut up. And also the decode of it. So it's, like, six things
versed saffron
what level?
heavy jackal
5 kyu
versed saffron
that's not too bad for 5
heavy jackal
oh look, it's the function that I knew must exist but couldn't remember it or see it in the references: ord()
quick ledge
def least_larger(array, index):
return sorted(array).index(array[index]) + 1
print(least_larger([4, 1, 3, 5, 6], 0))
@versed saffron
i feel it is cheating since I sort the array
versed saffron
would that not mutate the indices tho?
heavy jackal
what happens if you're given a 5, but there's another 5 in the list?
versed saffron
doesn't matter, return the first instance
I didn't think that far ahead actually
but I passed them all so 🤷♂️
quick ledge
def least_larger(array, index):
return array.index(sorted(array)[sorted(array).index(array[index]) + 1])
print(least_larger([4, 1, 3, 5, 6], 0))
looks ugly
but works
versed saffron
still better than the enum answers
quick ledge
wait i gotta make one more change so that it will return -1
but it will just make it even uglier 😂
def least_larger(array, index):
return array.index(sorted(array)[sorted(array).index(array[index]) + 1]) if array[index] != max(array) else -1
print(least_larger([4, 1, 3, 5, 6], 0))```
@versed saffron

versed saffron
that is not

like it's just cutting off letters
versed saffron

frozen thorn
have no idea what I'm doing wrong
def least_larger(a, i):
answer = []
for inc in a:
if inc > a[i]:
answer.append(inc)
return -1 if answer == [] else a.index(answer[0])
btw it's been awhile
versed saffron
min(ans) works too
frozen thorn
Omg it passed
versed saffron
congrats
frozen thorn
lol ty. I accidently typed a.sort() instead of answer.sort()
thought I was missing something
anyway to do this without for loop?
versed saffron
you can't
you can use list comp but you need to iterate through them
ig you can use enum but it's 'pretty much' the same thing
frozen thorn
I see. Should I learn list comp? I prefer "normal" code lol
actually, list comp looks fun
versed saffron
list comp's super nice when you need to generate a 'simple' list and want it in 1 line
@property
def armour_list(self):
return [getattr(self.Armour, attribute) for attribute in self.armour_slots]```List comp is actually very nice to use
versed saffron
not a great example but I just did that
heavy jackal
concise and efficient
sonic river
any idea why this is happening
@versed saffron in case you haven't solved it yet, look what happens when characters have multiple occurences in the string
frozen thorn
what's wrong with this? answer = [for inc in a if inc > a[i]]
versed saffron
wth why would that affect it?
heavy jackal
you need something before your for
frozen thorn
oh oops
sonic river
.index, numpy
versed saffron
but im not mutating the original string?
ohh
shit maybe I can't do this in one line
sonic river
you can
versed saffron
do i need to replace chars in the string?
sonic river
no, you can't do that in python anyway
look into enumerate
it's sensibly the same thing as your solution
but with something other than .index
(and a tiny bit longer tho)
versed saffron
oh ok I see how to use it
I've actually been meaning to learn it but I've never had a use
sonic river
I think you don't need the .lower() btw, isn't the input constrained to only alphabetical characters ?
heavy jackal
https://www.codewars.com/kata/5877e7d568909e5ff90017e6/python I understand the problem but not how to tell the computer how to do it. I think that means that I should stay on this problem so that I learn.
frozen thorn
def least_larger(a, i):
answer = []
s = [answer.append(inc) for inc in a if inc > a[i]]
return -1 if answer == [] else a.index(answer[0])
ah right
frozen thorn
Getting better
versed saffron
does capitalize() switch cases around?
versed saffron
maybe?
quick ledge
swapcase() does
sonic river
oh wait
quick ledge
capitalize just makes the firdst character of the string uppercase
heavy jackal
maybe you can use title()?
versed saffron
or (c+c*i).lower().capitalize()
quick ledge
#bot-commands message
it (capitalize()) only capitalizes the very first character of the string
versed saffron
I'll try title tho didn't know that was a thing
versed saffron
def accum(s):
return "-".join([(v*(c+1)).title() for c, v in enumerate(s)])```kata so fun

def sum_digits(number):

how's my logic?

@rough sapphire no, I'm going to take a break maybe for the day and let it percolate. My first idea involved recursion but that might not be necessary
rough sapphire
yeah recursion wont work
it will be 1e17 calls
I think there is some greedy way to do this
@frozen thorn why not modify the number directly instead of making it to string and then using that string
frozen thorn
hm Idk how to access first digit. That's why I converted int to str
narrow pecan
@frozen thorn what’s up with the nick?
frozen thorn
haah I forgot
rough sapphire
while number > 0:
total += number % 10
number = number // 10
return total
to add that name

from collections import Counter
from string import ascii_letters
def is_pangram(s):
for i in ascii_letters:
if Counter(s.lower())[f"%s"%i] >= 1:

return valid```
anyway to golf that? im lostI could convert it to str then add it to total like this total += int(s)
so no need for string = []
versed saffron
that's weird actually if I use [chr(i) for i in range(ord('a'),ord('z')+1)] it works but ascii_letters doesn't
frozen thorn
Ya, my idea works
def sum_digits(number):
total = 0
for s in str(abs(number)):

lol i attempted list_comp = [total += int(s) for s in str(abs(number))], Looks like I need to learn more about list comp
code format is annoying

You are not allowed to use that command here. Please use the #bot-commands channel instead.

Could you explain how module works with this?
rough sapphire
which module?
frozen thorn
I meant modulo
rough sapphire
its the remainder you get after you do division
frozen thorn
Ya
frozen thorn
hmm
rough sapphire
lets say you want to find a % b
it is equal to
r = a - k * b
where K is integer division of a and b
K = a / b
frozen thorn
ah i thought k is the remainder
frozen thorn
what does x do here? Is it just a variable?
rough sapphire
x is any number
frozen thorn
oh so an assign?
rough sapphire
I mean to write number % 10 but i am lazy 🥴
no x % 10 just gives you the remainder when x gets divided by 10
frozen thorn
sry lol. Where does the number in x come from? How does it know which remainder?
frozen thorn
do you have to assign to x then?
rough sapphire
yes
frozen thorn
That's why i was confused. Like why does x even exist. now i get it..
rough sapphire
lol sorry for confusion. I am bad at explaining things
versed saffron
sorry to interrupt
def delete_nth(order,n):

frozen thorn
hm anyone wanna help me with this kata? Don't think i understand the desription or there's not enough test cases
frozen thorn
Your team is writing a fancy new text editor and you've been tasked with implementing the line numbering.
Write a function which takes a list of strings and returns each line prepended by the correct number.
The numbering starts at 1. The format is n: string. Notice the colon and space in between.
rough sapphire
your code is above right?
I think you can just run a for loop and modify the list itself
frozen thorn
ah i got it
def number(lines):
result = []
n = 1
for char in lines:
result.append(str(n)+": "+char)
n += 1
return result
yep
frozen thorn
I thought I had to use dict
I mean the description was not clear enough lol and there's only 1 test case
So i thought "a" is always "1: a"
quick ledge
I got it in my first try
frozen thorn

on my first try or in my first try 🤔 ?
btw @frozen thorn , try using enumerate
!enumerate
royal lakeBOT
quick ledge
lol
def number(lines):
for i, line in enumerate(lines):
lines[i] = f"{i+1}: {line}"
return lines```ya
quick ledge
should have appended to a new list, but w/e
frozen thorn
can you do that with list_comp?
rough sapphire
yes
quick ledge
I was actually gonna see if I can do with list comprehension
rough sapphire
def number(lines):
return [f"{i + 1}: {line}" for i, line in enumerate(lines)]

yeah that's right

Ah I need to learn latex
buoyant pendant
lol
huge table sounds good to me haha
thanks for explaining it 🙂
i've seem some people take notes using latex in real time and that just blows my mind.. probably the same people that use all the VI shortcuts lol
honest star
Once you get used to the latex syntax it's amazing for math notes
I am faster in latex than I am hand writing equations, even for complex stuff
buoyant pendant
haha exactly
honest star
ha no, I think my comfortable rate is 80-100, 110+ if I focus
buoyant pendant
i consider myself a pretty fast typer, but i cant get anywhere as fast speed as handwriting. taking notes in latex would help me so much
my handwriting becomes unreadable after ~20min of writing
anything after that is me clenching a pen and squiggly lines resembling letters
solid pollen
I consider myself a lazy typer, I do around 40 WPMs, 60 if I focus lol
And my handwriting just is unreadable
buoyant pendant
i get like 70wpm :/
spare thistle
Bro I feel the handwriting, I average 90 WPM and can't write for the life of me
mild abyss
Ad my handwriting just is unreadable
@solid pollen u havent seen mine yet xD

I have a very hard time putting letters in the right order lately weirdly enough, so it is even worst, they are letters squishing in between and things like that lol

Yoo has anyone ever had a class where it took them away from programming? Currently doing a class with a ton of Haskell and finite state machines. Coding for 8 hours a day I simply don’t enjoy programming anymore

haskell rip
lunar shore
I code 10 hours a day
And I still love coding
And Haskell is awesome bruh
What's the problem with it
Haskell is great
Proceeds to write an essay

Probably it’s the way it’s presented for me and what we’re expected to do. Well briefly get an explanation on a concept and fully implement it. It’ll take me about 4 5 days just for setting up

https://dpaste.org/RJiQ I still need to add additional constructions and I havent started on nondeterministic machines, then I start on my assignment to have to conversion between machines.
I looked for possible haskell tutors but from haskell community most are just like learn yourself and come to freenode if you need help, but I get stuck too frequently
lunar shore
You can learn yourself
Half this server's community are self-taught
Also
http://learnyouahaskell/ is nice , currently following it personally
ig u have to go with chapter 9+
Since you know types and data and typeclasses

reading the chapters would like give me the rest of the foundation to get things done easier?
But thanks just making it seems manageable makes it seem less of torture

oh lol i did a class with some lisp variation called racket
it was a pain at the start
but it provides a new perspective after ur done

print(len([x for x in arr if x in smile))
This would be my solution to it
Not worth 6 kyu at all
imho

I did
quick bay
good good
frozen thorn
Just wondering. Did you have to look up these builtin funcs or did you know it already?
coral void
I've learned them all over the years
sum() is pretty useful, itertools.product() as well
generally though it's a case of "Right, that's a combination of things, therefore there's probably something in itertools to make it", and "counting? sum"
as well as they "checking for inside a lot? set"
frozen thorn
Oh I see
According to kata's ranking system
Yellow (Novice)
complex language features
simple algorithms
I guess that makes sense
frozen thorn
anyone know why this doesn't throw error in codewars but it does in repl.it?
def factorial(n):
result = 1
try:
if n > 0 and n <= 12:
for x in range(1, n+1):
result *= x
return result
elif n == 0:
return 1
else:
raise ValueError
except ValueError:
return 'Sorry, Try again.'
what is the error?
frozen thorn
just that if the number is less than 0 and greater than 12 then should raise ValueError
Should i add condition?
quick ledge
oh, did you mean codewars isn't throwing an error though you are raising one
frozen thorn
Yeah. Is there a difference?
lunar shore
u better use a condition for this one
frozen thorn
import math
def factorial(n):
try:
if n >= 0 and n <= 12:
return math.factorial(n)
elif n < 0 or n > 12:
raise ValueError
except ValueError:
return 'Sorry, Try again.'
Still didn't work. Weird
lunar shore
Just use a condition
quick ledge
did the indentation carry over properly?
lunar shore
import math
def factorial(n):
if n >= 0 and n <= 12:
return math.factorial(n)
return 'Sorry, Try again.'
This would be if I would do it ^^^^
frozen thorn
oh i see. I did this
import math
def factorial(n):
if n >= 0 and n <= 12:
return math.factorial(n)
raise ValueError('Sorry, try again')
You can do that
frozen thorn
It said to throw ValueError
lunar shore
But it'd not return a value if it gave error
It just gives an error
And your program would be terminated
If that's what you want , do it
frozen thorn
Yeah i get it. Idk why kata asks to raise ValueError if conditoin is false
lunar shore
¯_(ツ)_/¯
frozen thorn
Is this bad practice?
frozen thorn
I'm trying to use ternary operator for this.
lunar shore
Oh it'd not be so hard
frozen thorn
Well, this is what I got return math.facorial(n) if n >= 0 and n <= 12 else raise ValueError('Test'), I'll figure it out
lunar shore
(n >= 0 && n <= 12) ? math.factorial(n) : NULL;
If I were to do it in cpp ^
wheat lynx
I think raise ValueError isn't an expression isn't an expression so that wouldn't work?
lunar shore
Oh he needs an expression?
frozen thorn
I need to raise ValueError if the condition is false. What can I do if I can't use return or raise in ternary operator?
lunar shore
print probably
Or pointers if it's C++
I mean , in Python you can use immutable objects
An example could be :
def factorial(n): # n is an array with one memeber : The number you want
n[0] = [math.factorial(n) if n >= 0 and n <= 12 else None][0]
Would change n's first element to the answer , if I'm not wrong
And if n is not satisfying the if , it is gonna be n = [None]
frozen thorn
I see. But, I have to raise ValueError though. I can't do n = [ValueError can I?
lunar shore
You can check for n's value
but
u said u don't want raise?
ohhh
I mean
u can make n return a valueError
Probably define it to something that is gonna give val err
Maybe do this :
def factorial(n): # n is an array with one memeber : The number you want
n[0] = [math.factorial(n) if n >= 0 and n <= 12 else int("gives a value error probably")][0]
Try that probably yeah
Not sure if that only works in lazy langs like haskell or not
But should give it a try
frozen thorn
Hmm. Prob not possible to raise an error oneline
lunar shore
But try that
frozen thorn
But it wants ValueError throw. None, or other errors won't work
frozen thorn
TypeError: 'int' object does not support item assignment
frozen thorn
Yeah lol
lunar shore
I thought you are implementing a func
frozen thorn
ah mb
frozen thorn
Yeah that's what i used
lunar shore
Mhm that'd work
frozen thorn
Can't do that in oneline because I can't use raise or return after else
frozen thorn
Ya. This is what I used
import math
def factorial(n):
if n >= 0 and n <= 12:
return math.factorial(n)
raise ValueError('Try again')
import math
def factorial(n):
if n >= 0 and n <= 12: return math.factorial(n)
raise ValueError('Try again')
Probably short
frozen thorn
ooh
lunar shore
Oh waaaiit
In one line
It could be this :
import math
def factorial(n):
return math.factorial(n) if n >= 0 and n <= 12 else int("Try again")
Try this
frozen thorn
I thought int() convert string to an integar? Will try it
Oh i see it throw an error
lunar shore
ValueError
If that didn't work either
Try :
import math
def factorial(n):
return math.factorial(n) if n >= 0 and n <= 12 else ValueError("Try again")
Yeah, no one has done this in oneline
lunar shore
XD
frozen thorn
lol
lunar shore
Well , i did now lmao
frozen thorn
frozen thorn
where?
lunar shore
Submit my code and you'll see
frozen thorn
it works tho
lunar shore
mhm
frozen thorn
import math
def factorial(n):
return math.factorial(n) if n >= 0 and n <= 12 else int("Try again")
huh it passed all for me
lunar shore
and like the 9th
frozen thorn
did you use int()?
frozen thorn
Yeah i submitted lol
lunar shore
Oh wait
Lemme try again
Mhm worked
Welp
Congrats to us , the only one line solution lmao
frozen thorn
lol
lunar shore
or idts ...
factorial=lambda n:__import__("math").factorial(n)if 0<=n<13 else int("x")
Look at this dude ....
frozen thorn
How did you know that int() will throw ValueError? I tried googling which built in function will throw ValueError in python
oof
lunar shore
Well , experience
frozen thorn
Ya.
lunar shore
But he also did the int(string) thing too
Well , the only one line solution without lambda
frozen thorn
haha
frozen thorn
1 similar code variation is grouped with this one lol

⊕ for subtraction. interesting
frozen thorn
For the first test case Sana can choose x=4 and the value will be (6⊕4) + (12⊕4) = 2+8 = 10. It can be shown that this is the smallest possible value.
lunar shore
wow lmao
Oh no
(logic) exclusive or. (logic) intensional disjunction, as in some relevant logics. (mathematics) direct sum.

I’m gonna make a study app, it’s gonna be called studify, (original, ikr) it’s gonna make it easier in general to study and save digital notes you want to easily access, and such. What you guys think?
gaunt willow
It's an idea that has been done to death, but if you want to just do it as a fun side project it could be cool
honest star
What kind of functionality would it have? How would you make it easy to save and access the digital notes?
rich moon
although the idea of a study app has been done a lot of times, but personal features that are different than the others out there makes it cool
young shoal
the idea of typing up notes on a phone keyboard is kinda scary
esp when you need to draw or have mathematical equations
rich moon
hence u add a feature for typesetting
young shoal
sure, but go on your phone rn and try to type a basic function like
def addition(a: int, b: int) -> int:
return a + b
unless you cram everything into one section, typing equations is just going to be slow and annoying
young shoal
well then you're really gonna have to come up with something innovative
there are already soooooo many things that do that
such as one note
honest star
between notion and one note I'm pretty well covered for notes
rich moon
type setting feature seems nice
maybe giving suggestings on how to allocate time would also be a nice feature
