'match' is a soft keyword since Python version 3.10 (see https://docs.python.org/3/reference/lexical_analysis.html#keywords), therefore I wouldn't use it as a variable name now.

It was likely intentional. Appending to a list is O(1), so they create the string only once at the end using 'join'. However, concatenating two strings creates a new string each time, which can be a costly operation.

Not sure if it was on purpose, but I believe making "L" a list is less efficient than making it a string.

Variable names evoke sadness

You know, magic ¯_(ツ)_/¯

how did six people use the same names and stuff and then get best practices?

Can someone please explain to me how this code works? How is it capitalizing through a for loop?

yeah, that's the kata

this logic only finds one missing character.

Is it work when rgb(-10, -10, -10)?

Your code us clear. But I think the program description is the result larger than 140. The input is not. Since the input contains many spaces , the input is always larger than the result. So , although input is larger than 140 , the result may not larger than 140. So , your code does not work welll if the input is larger than 140 while the result is not.

couldn't help but notice the count = count + 1 lol, use count += 1. only problem I had, great work

Slicing is your friend!

how did you get this dict

I think that the test for equality covers the '' case too.
