the function "enumerate" is so cool!

Took me a few iterations to get this one liner.

i refused to admit that you guys got this solution the first time you went through

Yes, but kata solutions don't necessarily have to be efficient (unless the kata tests explicitly require them to be such).

I see. Thank you for clarifying. I've never used Python 2, so I wouldn't know. Haha!

This solution is for Python 2, and that's been already mentioned 7 years ago by runzhi214 and frankturnerv.

In other programming languages, like JavaScript, it returns a returns a new array from an original array based instructions you give it. It works similarly in Python, only the list isn't return. It iterates through a list and applies changes you've specified using a function to each element in the list, or multiple lists. I hope this helps some.

wow, it's clever

here are few examples to simplify it:
map(int, a) --> apply int to every list object in list a to make them integers
map(str, a) --> apply str to every list object in list a to make them strings

Love it

Awesome!

they were?
