通过python的tkinter实现简单的注册登录

参考文章:

编写一个用户登录界面,用户可以登录账户信息,如果账户已经存在,可以直接登录,登录名或者登录密码输入错误会提示,如果账户不存在,提示用户注册,点击注册进去注册页面,输入注册信息,确定后便可以返回登录界面进行登录。进入个人主页可以对个人信息进行修改。

代码

import tkinter as tk
from tkinter import messagebox  # import this to fix messagebox error
import pickle
username = ''
# 登录界面
def welcome():
    def usr_login():
        usr_name = var_usr_name.get()
