Using the standard GUI library for Python, Tkinter, developers can seamlessly craft desktop applications. Among its myriad features, one standout is the capability to present message boxes to users.
To make the most out of Tkinter, it’s recommended to use Python 3 or newer versions, as Python 2 is now deemed outdated. For clarity on your Python version, a simple command can be executed:

1
python --version

tkinter menu bar

Leveraging the Power of the Tkinter Toolkit: Crafting a Main Menu Bar
For many Python GUI applications, the main menu is not just a feature; it’s the nucleus. Being the focal point, it is the bridge that connects users to various app functionalities.
Here’s an illustrative example of what a menu crafted with Tkinter looks like:

Constructing the Tkinter Menubar

Designing an intuitive menu using Tkinter is not a herculean task. Here’s a concise and detailed breakdown of the process. Take note that every menu item, like “New”, “Open”, or “Save”, usually maps to a unique callback function.

from Tkinter import *

def donothing():
x = 0

root = Tk()
menubar = Menu(root)
filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="New", command=donothing)
filemenu.add_command(label="Open", command=donothing)
filemenu.add_command(label="Save", command=donothing)
filemenu.add_separator()
filemenu.add_command(label="Exit", command=root.quit)
menubar.add_cascade(label="File", menu=filemenu)

helpmenu = Menu(menubar, tearoff=0)
helpmenu.add_command(label="Help Index", command=donothing)
helpmenu.add_command(label="About...", command=donothing)
menubar.add_cascade(label="Help", menu=helpmenu)

root.config(menu=menubar)
root.mainloop()

The journey of crafting a main menubar kicks off with this fundamental call:

1
menubar = Menu(root)

In this context, root denotes the core Tk() instance.

Menus in graphical interfaces often house a collection of submenus. These can range from File to Edit to View or even Tools. To create these submenus, the pattern remains consistent, utilizing the Menu() call:

1
filemenu = Menu(menubar, tearoff=0)

The final step in the process involves populating these submenus with individual menu items using the add_command() method:

1
filemenu.add_command(label="New", command=donothing)

In our demo here, the donothing() function is a placeholder callback for each menu item. However, in real-world scenarios, every menu item would point to its specific callback function.
