i like it

Pep8 recomends not to use complex compound statements, like if len(x for x in list) > len (y for y in range(6): return [x for x in list] if A else 0
This is fine i guess

Very easy to read too!

0-5 == -5 right? :)
thats why it works

I like your solution... very clever

I - indentation.

best and beast practice.

Would have never thought of this..

Thank you all

Arrays with negative numbers are not generated in the tests, but still for the array [-1, -2, -1, 0] your solution will return -1, although the correct index is 1.

Thanks for the info lechevalier -- I was really wondering what the problem was.
