NameError: name 'num' is not defined

I can't figure out what's wrong with my code. I keep getting the error message NameError: name 'num' is not defined. Please help.

even.py 
import random

even_odd = num
num = random.seed
if num % 2 == 0:
    print("True")
else :
    print("False")

You need to set num before you use it to set even_odd

You have the right idea. The syntax needs to be corrected:

import random

def even_odd(num):  # <-- correct function definition
    # num = random.seed  # <-- 'num' passed as argument
    if num % 2 == 0:
        return True  # <-- return not print
    else :
        return False  # <-- return not print
