有一种循环叫死循环,一经触发,就运行个天荒地老、海枯石烂
海枯石烂代码
count = 0 while True: print("你是风儿我是沙,缠缠绵绵到天涯...",count) count +=1 # 相当于 count = count +1
其实除了时间,没有上面是永恒的,死loop还是少写为好
上面的代码循环100次就退出吧

count = 0 while True: print("你是风儿我是沙,缠缠绵绵到天涯...",count) count +=1 if count == 100: print("去你妈的风和沙,你们这些脱了裤子是人,穿上裤子是鬼的臭男人..") break
回到上面的for循环的例子,如何实现让用户不断的才年龄,但只给最多3次机会,再猜不对就退出程序。

#!/usr/bin/env python # -*- coding: utf-8 -*- my_age = 28 count = 0 while count < 3: user_input = int(input("input your guess num:")) if user_input == my_age: print("Congratulations, you got it !") break elif user_input < my_age: print("Oops,think bigger!") else: print("think smaller!") count += 1 #每次loop 计数器+1 else: print("猜这么多次都不对,你个笨蛋.")
