Tkinter code Works in Windows but not in Mac

Question

Why does the following test not display the menu on my Mac running Python 3.7 on Mojave?

Tried a shebang but that didn't help.

import tkinter as tk

def quit_app():
    my_window.destroy()

    my_window = tk.Tk()
    my_menu = tk.Menu(my_window)
    my_menu.add_command(label='Quit',command=quit_app)
    my_window.config(menu=my_menu)
    my_window.mainloop()

The menu displays in Windows 10 but not on the Mac. The tkinter window is blank on the Mac.

Have you read e.g. https://stackoverflow.com/q/52529403/3001761? — jonrsharpe, Sep 10 '19 at 09:46

Yes, that is because MAC has a design philosophy that all devs for their platform have to conform with. You cannot have a add_command as a top level menu item on mac, rather:

import tkinter as tk

def quit_app():
    my_window.destroy()

my_window = tk.Tk()
my_menu = tk.Menu(my_window)
quit_menu= tk.Menu(my_menu, tearoff=0)
quit_menu.add_command(label='Quit App',command=quit_app)
my_menu.add_cascade(label="Quit", menu=quit_menu, underline=0)
my_window.config(menu=my_menu)
my_window.mainloop()

line 4, in quit_menu.add_command(label='Quit App',command=quit_app) NameError: name 'quit_app' is not defined – TamP Sep 11 '19 at 13:51
check the updated code format above. You did not define the `quit_app` function. – Samuel Kazeem Sep 11 '19 at 17:09
