Python Tkinter Messagebox: Display messages

Last update on April 25 2025 12:53:43 (UTC/GMT +8 hours)

Write a Python program that displays messages in a messagebox using Tkinter.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import messagebox

# Create the main window
parent = tk.Tk()
parent.title("Messagebox Example")

# Function to display a message in a messagebox
def show_message():
    messagebox.showinfo("Message", "Hello!")

# Create a button to trigger the messagebox
button = tk.Button(parent, text="Show Message", command=show_message)
button.pack()

# Start the Tkinter event loop
parent.mainloop()

In the exercise above, we create a “Tkinter” window with a button labeled "Show Message." When you click the button, it calls the "show_message()" function, which displays a messagebox with the title "Message" and the message "Hello!".
