#Create a Menu Bar
menuBar=Menu(app)
app.config(menu=menuBar)

About the code

First, I am importing the tkinter modules.

Next, assign a class and variables and give application title.

Next, create menu bar and add menu item in menu bar.

Next, create ask message function and add “Yes” or “No” or “Cancel” options in displaying file close menu.

Finally, I have started the windows event loop by calling the mainloop method then execute the code.

Then, let’s execute the code.
