wut did I just read

very cool

beauty indeed

Way late here, but for anyone else reading this: An <odd> % 2 == 1, and an <even> % 2 == 0, both of which can be interpreted as the boolean True (1) and False (0) in Python, respectively. So line 3 is essentially saying odd = True, even = False.

When a string is passed to a boolean evaluation, the empty string '' returns False. Any non-empty string returns True. So "not string" is True if the string is non-empty, False if empty.

What "return not string" mean?

Yeah, this thing is like o(n^2), how does this thing have any best practice votes for it?

time complexity is just awful... ;o

This is a really slick solution. Not only is it readable (for me anyways) its also very short. 10/10

Really very elegant solution.

hehe thats funny, not the best in terms of complexity i think, but still clever:)

Ah yes, I see it now. Very elegant method.

I need to remove all non-parentheses characters for this: string.replace("()", "")

Oh right, the return not string line only works if the string contained only parens at the start. Nice!
