实现让用户不断的猜年龄，但只给最多3次机会，超过次数猜不对就退出程序。

#!/usr/bin/env python# -*- coding: utf-8 -*-# __author__ = "Sandu"

my_age = 27count = 0

while count < 3:   guess_age = int(input("请输入您猜的年龄："))   count += 1   if guess_age > my_age:      print("年龄猜大了")      if count == 3:         print("已经超过输入次数了")   elif guess_age < my_age:      print("年龄猜小了")      if count == 3:         print("已经超过输入次数了")   else:      print("恭喜你，猜对了！")     break
