Python 编写登录接口(第一天)

作业：编写登录接口

• 输入用户名密码
• 认证成功后显示欢迎信息
• 输错三次后锁定

import sys #标准库
import os #标准库，不需要安装插件
import getpass   #引入getpass模块
class Login():   # Login类
    def userInfo(self,userInfoAddr):
        #将用户名密码信息处理成一个字典
        with open("userInfo","r+") as file:

                user_List = i.split(":")
                user_dic.update({user_List[0]:user_List[1].rstrip()})
        return user_dic

        #将否定的文件处理成一个列表
        with open("lock_Info","r") as file:
            userList = []
            for i in file:
                userList.append(i.rstrip())
        return userList

    def lockUser(self,username):
        #如果相同用户登录三次就调用此函数，该用户将永久锁定，写入文件
        with open("lock_Info","a") as file:
