你不应该在 python 2 或 python 3 中使用 tk_menuBar.该函数的文档字符串是这样说的:

You should not be using tk_menuBar in either python 2 or 3. The docstring for that function says this:

"""请勿使用.在 Tk 3.6 及更早版本中需要."""

"""Do not use. Needed in Tk 3.6 and earlier."""

注意:tk 3.6 在 90 年代初就过时了.

Note: tk 3.6 went obsolete back in the early 90's.

无法将菜单附加到 Frame 小部件.您可以添加 Menubutton 的实例来模拟菜单栏，但不会得到真正的菜单栏.

There is no way to attach a menu to a Frame widget. You can add instances of Menubutton to simulate a menubar, but you won't get a real menubar.

您可以通过配置menu 属性将Menu 附加到根窗口或Toplevel 的实例.

You can attach a Menu to the root window or to instances of Toplevel by configuring the menu attribute.

import tkinter as tk

root = tk.Tk()

menubar = tk.Menu()
fileMenu = tk.Menu()
editMenu = tk.Menu()
viewMenu = tk.Menu()

menubar.add_cascade(label="File", menu=fileMenu)
menubar.add_cascade(label="Edit", menu=editMenu)
menubar.add_cascade(label="View", menu=viewMenu)

root.configure(menu=menubar)

root.mainloop()
