Not sure how to use even_odd??

Hi All,

A little stuck here...

Im not sure how to use the even_odd function?? this is throwing me off....

even.py 
import random
start = 5
while start == True:
    random.randint(1, 99)
    (start - 1)

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

Don't worry about figuring out how the even_odd function works. All it does is that is returns True if the number you pass in is even or else it will return False.

we can just return the remainder of num / 2 (with num % 2), but because this returns whether a number is odd or not and the function is supposed to return whether a number is even or not, we need to reverse whatever value comes out of num % 2
