Day1_Python基础_15.while loop

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

其实除了时间，没有什么是永恒的，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for 循环的例子，如何实现让用户不断的猜年龄，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.")
