When your application allows you to perform more than one action, a menu is frequently the most common way to allow access to those actions:
The tkinter.Menu class allows us to create menus, submenus, actions, and separators. So, it provides everything we might need to create basic menus in our GUI-based application:
import tkinter
def set_menu(window, choices):
menubar = tkinter.Menu(root)
window.config(menu=menubar)
def _set_choices(menu, choices):
for label, command in choices.items():
if isinstance(command, dict):
# Submenu
submenu = tkinter.Menu(menu)
menu.add_cascade(label=label, menu=submenu)
_set_choices(submenu, command)
elif label == '-' and command == '-':
# Separator
menu.add_separator()
else:
# Simple choice
menu.add_command(label=label, command=command)
_set_choices...
