我正在使用这段代码来制作一个文本编辑器，我正在尝试添加菜单和快捷方式，我将在稍后植入它到现在我不知道该怎么做（如果你知道答案，那是另一天的另一个问题请分享它。但无论如何我收到此错误，我不知道为什么。错误：

    Traceback (most recent call last):
        File "C:\Python27\Completed Projects\editor.py", line 90, in <module>
          Editor().mainloop()
        File "C:\Python27\Completed Projects\editor.py", line 52, in __init__
          filemenu.add_command(text='Save',  command=self.onSave).pack(side=LEFT)
        File "C:\Python27\lib\lib-tk\Tkinter.py", line 2683, in add_command

您的问题可以通过简单地更改text为来解决label。例如：

filemenu.add_command(text='Save',  command=self.onSave)

应该

filemenu.add_command(label='Save',  command=self.onSave)
