Posted 2020-10-26 jacky1015

要求：

1、输入用户名和密码

2、认证成功后显示欢迎信息

3、输错三次锁定

Python实现代码如下：

# -*- coding: UTF-8 -*-
C = 0
name = "quan"
passed = 123
while C < 3:
    username = input("username:")
    password = int (input("password:"))
    if username == name and password == passed:
        print("welcome!")
        break
    C = C + 1
    if C == 3:
        print("you Enter the wrong lock three times！")
