AttributeError: module 'rules' has no attribute 'fizz'

Question

So I tried to create a fizz buzz game code in python and I wanted to import the rules from another file,

import rules

fizz = rules.fizz
buzz = rules.buzz
fizzbuzz = rules.fizzbuzz


def fizz_buzz(input):
    if input % fizz == 0:
        result = "Fizz"
    elif input % buzz  == 0:
        result = "Buzz"
    elif input % fizzbuzz== 0:
        result = "Fizzbuzz"
    else:
        result = input
    return result

i = 1
while i < 1000:
    print(fizz_buzz(i))
    i += 1

fizz = 3
buzz = 5
fizzbuzz = fizz*buzz
