damn

oh got it

Because for char in s, we are iterating over each character in the string s, and for each character c, we are multiplying it by 2 (c * 2) to create a new string with the character repeated twice. The join() method is then used to concatenate all the doubled characters into a single string.

🤡 <-- This is me finding out this method exists

This is really quite novel. Nice!

It's not dissimilar to a 'for' loop with a list. Think of it as 'for [any item] in [what I'm telling you to look at]'.

In this case we're telling the program to look at a string, so the 'any item' is just 'any/each individual letter'. 'C' is simply a placeholder for that.

I appreciate this is checks watch 11 months late, but I hope it helps if you ever return here!

here i am make a whole for loop LOL

broooooo

Cursed

today i learned

Whaaaaat??!!!

New thing learned! Achievement unlocked!

I was totally unaware of the existence of that method in Python.

It is a generator btw.
