Python求两数的最大公约数

import math

while True:
    num1 = int(input('请输入第一个整数'))
    num2 = int(input('请输入第二个整数'))
    if num1 > num2:
        while num2 != 0:
            num1, num2 = num2, num1 % num2
        print(num1)
    elif num1 < num2:
        while num1 != 0:
            num2, num1 = num1, num2 % num1
        print(num2)
    else:
        print(num1)
