get'typeError：insertstop（）采用0个位置参数，但给出了1个。当我的函数调用中没有参数时

Question

我是Python的新手，我正在尝试将我的第一个应用程序放在一起，将旅行信息插入并将其插入文本框中以导出到文档中。直到今天，当我尝试实现多种方式将文本从入口箱中插入文本块中的多种方式，它的发展都非常好。

我有一个输入小部件，可以在按下按钮时将文本插入文本小部件。这很简单，但我想让它进入可以直接点击Enter键做同样的事情的地方。

当我实现此功能时，我会收到错误：

“ tkinter回调中的异常 Trackback（最近的最新电话）： 文件“ C：\ Program Files \ Spyder \ PKGS \ tkinter_ init _。py”，第1892行，在__呼叫__ 返回self.func（*args） TypeError: insertstop() takes 0 positional arguments but 1 was given"

I've looked the error up and it seems like it would pop up if I put in arguments in my function call but I don't have any arguments in any of my function calls. Also it seems like maybe this error is related to a class or something? I haven't learned about classes yet and only have a basic idea of what they are. Do I need a class to do this?

Coincidentally I also added the argument(self) in my function and that made pressing enter work but it made my insert stop button quit working.

I'm sure I've missed something very basic but I just can't figure out what.

Thanks for any help!
