使用python的tkinter模块实现的GUI版用户登录程序（附源码）

在登录界面&＃xff0c;用户可以选择直接登录&＃xff0c;也可以选择注册账号

登录时&＃xff0c;如果用户名不存在&＃xff0c;会询问是否注册&＃xff0c;如果用户名存在并且密码正确&＃xff0c;则登录成功

用户名不存在

密码错误

登录成功

用户注册时&＃xff0c;需要用户输入用户名&＃xff0c;密码&＃xff0c;和再次确认的密码&＃xff0c;当两次输入的密码相同时才能成功注册&＃xff0c;在注册时&＃xff0c;用户也可以取消注册

密码输入不一致

注册成功

取消注册

每个部分都分成了一块&＃xff0c;每个部分的功能都用注解标注了&＃xff0c;可以对比功能看一下代码
