If return not 0 turn falsey to true, wouldn't return not 1 make it falsey?

This is from even_odd question under python basic.

def even_odd(num):
    # If % 2 is 0, the number is even.
    # Since 0 is falsey, we have to invert it with not.
    return not num % 2

Correct. The 1 means it was an odd number. Since 1 is truthy, not 1 is False. Therefore return not 1 will return a False if an odd number is submitted.
