这次的Python Tkinter窗体登录程序模板还是之前的，在此基础上进行了改进，这一次是通过创建一个新的列表和字典来存储和验证账号和密文（加密后的账号和密码）；第一次的窗体登录程序是通过连接SQL数据库来存储账号和密码。
这是我自己将其封装后的代码，控件的位置是用相对位置表示，只能调用类里面的主函数Main()。

这里还有一个是非窗体程序代码，也是通过列表和字典来实现的，
封装后的代码如下：

以上就是主要代码，这次是通过新建列表和字典来存储和验证账号和密码，感兴趣的小伙伴可以来看看，可能还有一些不足之处，也欢迎大家指出。之前我是通过连接SQL Server数据库来实现：Python Tkinter窗体程序连接SQL Server数据库实现账号登录、账号注册等功能。
