Python Tkinter event handling: Button clicks

Last update on April 25 2025 12:53:44 (UTC/GMT +8 hours)

Write a Python program that implements event handling for button clicks using Tkinter.

Sample Solution:

Python Code:

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Button Click Event Handling")

# Create a label widget
label = tk.Label(root, text="Click the button and check the message text:")
label.pack()

# Function to handle button click event
def on_button_click():
    label.config(text="Button Clicked!")

# Create a button widget
button = tk.Button(root, text="Click Me", command=on_button_click)
button.pack()

# Start the Tkinter event loop
root.mainloop()

In the exercise above, we create a "Tkinter" window with a label and a button. When the button is clicked, it calls the "on_button_click()" function, which changes the text of the label to "Button Clicked!".
