我正在开发一个程序，该程序允许用户存储其用户名和密码，并对存储它们的纯文本进行哈希处理（因此注释掉了哈希码）。但是，我将tkinter用于GUI，我的一个按钮在被调用之前会运行一个已定义的函数。（请忽略所有看似随机的评论）

如果运行此代码，然后按注册按钮，然后输入主用户名和密码，则应将它们都写入记事本文件，并且如果框中没有任何内容，则显示错误消息。但是，这些功能都不起作用。当用户按下主窗口上的第一个“注册”按钮时，它将（以某种方式）运行错误代码，并在出现错误代码之前给出错误代码。当在“输入主用户名和密码”窗口上单击“注册1”按钮时，错误代码应显示是否没有任何内容。我不知道为什么代码会提早运行。能否请您回答原因，甚至是固定代码？谢谢，Tf0R24。

定义的代码在使用tkinter按钮调用之前执行
