This was really hard to wrap my head around (probably because I don't know much of python) but I could understand that last answer. That's what I love about codewars; after submitting your solution, you will see the solution of other people and learn a better or easier way of solving the problem
Yeah, it is really cool. It was because of the solutions that I have now started trying to attempt some questions with a single line of code. It's working well so far.
