Check if a number is odd or even in Python [duplicate]

by 
if num % 2 == 0:
    pass # Even 
else:
    pass # Odd

The % sign is like division only it checks for the remainder, so if the number divided by 2 has a remainder of 0 it’s even otherwise odd.

Or reverse them for a little speed improvement, since any number above 0 is also considered “True” you can skip needing to do any equality check:

if num % 2:
    pass # Odd
else:
    pass # Even
