Well this is not correct in theory because the end should be the max
number, not the number of elements.
So it should be
[i*2 for i in range(10/2)] which might be fine but it's not really
more clear imho..

Changed it thanks

Thank you that's nicer, but ifiilterfalse is not in Python 3 (could
use filter of course).
