保存文件上下文时出错

Question

我一直收到一个错误，说当我按下按钮时，按钮无法调用函数。这里是它无法运行的函数

scroll.config(command=text.yview)
text.pack(fill=BOTH, expand=1)
root.mainloop()

错误代码

Traceback (most recent call last):
File "C:UsersHeroAppDataLocalProgramsPythonPython310libtkinter__init__.py", line 1921, in __call__
return self.func(*args)
File "c:UsersHeroDocumentsVisual Studio codeMy projectMainFrame.py", line 82, in savefile
myfile = open(filename, "w+")
TypeError: 'Button' object is not callable

这就是整个脚本和整个错误的全部内容。我希望这能有所帮助。我只是觉得如果我把整个代码作为它真正大的lol 发布，它会妨碍我

测试后，问题是将预定义的python变量分配给打开按钮。您所在的位置：

open = ttk.Button(barframe, text='Open', style='Accent.TButton')

只需将其更改为：

openButton = ttk.Button(barframe, text='Open', style='Accent.TButton')

然后下游更改为：

openButton.grid(row=0, column=1)
