37.猜数字游戏（0~100），猜猜电脑里存储的数字?

import random

while(c == 0):
	a = int(input("请输入0~100之间的任一整数（包括0和100）："))

	if a == b:
		print("是的，你猜对了！")
		c += 1
	elif a < b:
		print("你猜的数字小了")
	elif a > b:
		print("你猜的数字大了")

?38.两个整数间的最大公约数

a = int(input("请输入第一个数字："))
b = int(input("请输入第一个数字："))
m = max(a, b)
n = min(a, b)
r = m % n
while r != 0:
	m = n
	n = r
	r = m % n
print(a, "和", b, "的最大公约数为", n)
