code challenge not working

Not sure why this isn't working,

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

It has to do with your print functions in your while loop.

Python 3 requires you to pass the string to print in parentheses.

So instead of:

print "string"

You have to make it:

print("string")
