Task One Stops Passing

Whenever I hit Part 3 of this question, it tells me Task 1 no longer passes. And when I try to run my code in Task 1 without changing it back, it tells me there's a syntax error that I don't see.

Can anyone tell me where I'm going wrong?

even.py 
import random

start = 5

while start:
    random_num = random.randint(1, 99)
    if even_odd(random_num) > 0:
        print("{} is even".format(random_num)
    else:
        print("{} is odd".format(random_num)
    start--

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

Hey Roderick!

even odd spits out a boolean. try just checking that on its own. Just passed with the code below. it gave me the same, 'task one is not passing' but it was just because i was originally using the '{}' % var instead of normal format

import random

start = 5

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

while start:
    randnum = random.randint(1,99)
    if even_odd(randnum):
        print("{} is even".format(randnum))
    else:
        print("{} is odd".format(randnum))
    start -= 1

Thanks, David!

Admittedly I tried changing my code myself to look like yours (( that if even_odd(randnum) line ))and it didn't work, but copying and pasting your code DID work, so... I guess it's just something I wasn't seeing, hah.
