Python3.x tkinterpython3.9 中的 Entry 子类和用户输入重复的问题

第一个帖子，但很长时间的听众…

我刚接触Tkinter，遇到了一些问题.让我摸不着头脑的主要一点是，当我在4个输入框中的一个框中输入一个值时，它们会复制其他4个框中的值.按钮工作正常，我需要清理东西，但不确定这是否是一种有效的方法:

此外，框架是错误的，我计划添加 comments

我删除了一些无关的行，但得到了相同的结果.将self添加到Entry对象的Text变量中.

s.configure('Danger.TFrame', background='red', borderwidth=5, relief='sunken')

#Fix needed for inputs duplicating.
