Good solution, but i think it's not category "clear", maybe, "creative"...

Hi, i don't want to start a flame war, but what is not clear on this. It says exactly what it should do. I like it except from the redundant parentheses around the list().

Hi both, no flamewar here. :) My opinion on this simple code that is not a beautiful solution. That is quick and non-optimal, but semantically quite close to natural language. Let's say that's "Pythonic". There is no category for this kind of code ;) That's true for the parenthesis, I kept this habit.

List but not the least
