Create A Message Box That Asks Yes Or No

Intro

In this blog, I am going to create an ask yes or no message box in Python GUI application, when a user clicks "Close" from the action menu, it will ask for the user's choice as - yes or no - in the application screen.

Software requirement

Python 3.5 and IDLE (Python 3.5)

Programming code

#Create ask yes or no message Box in Python GUI Application
import tkinter as tk
from tkinter import ttk
from tkinter import Menu
from tkinter import messagebox as mbox
yes_or_no = tk.Tk()
#Add a Title
yes_or_no.title("Python GUI App")
#Label
ttk.Label(yes_or_no, text="Yes or No action Box").grid(column=0,row=0,padx=20,pady=30)
#Create a Menu Bar
menuBar=Menu(yes_or_no)
yes_or_no.config(menu=menuBar)
#Display a yes or no Message Box
def _msgBox():
mbox.askyesno('Yes or No action Box','Choose the action')
#Create Message Menu
infoMenu=Menu(menuBar, tearoff=0)
infoMenu.add_command(label="Close", command=_msgBox)
menuBar.add_cascade(label="Message", menu=infoMenu)
#Calling Main()
yes_or_no.mainloop()

About the code

First, I am importing the tkinter modules. 

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

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

Next, create the ask message function and add "yes" and "no" options in displaying command menu.

Finally, I have started the Windows event loop by calling the main loop method. 

Then, let's execute the code.
