Question

for x in xrange(12):
    if x % 2 == 1:
        continue
    print x

i know what it does, but the language doesn't make sense to me. In particular the second line is where i am lost.

% is a modulo operator. A detailed answer - http://stackoverflow.com/questions/4432208/how-does-work-in-python — gaganso, Jun 11 '16 at 03:24

if x % 2 == 1 means "if x modulo 2 equals 1".

Modulo (or mod) is the remainder after division. So, for example:

3 mod 2 = 1
12 mod 5 = 2
15 mod 6 = 3

For x mod 2, you're there's a remainder if and only iff x is odd. (Because all even numbers are divisible by two with 0 remainder.) Likewise, odd numbers will always have a remainder of 1.

So x % 2 == 1 returns true if x is odd.
