Tkinter - Close window programmatically

In Tkinter, you can close a window programmatically by using Tk.destroy() method.

To close a window in Tkinter programmatically, call destroy method on the Tk class object which is our window.

window = tk.Tk()
window.destroy()

In this tutorial, you will learn how to programmatically close the window in Tkinter, with examples.

Examples

1. Close window on Button click

In this example, we create a basic Tk window with a button in it. When user clicks on this button, we close the window using destroy() method.

Python Program

import tkinter as tk

# Create the main window
window = tk.Tk()
window.title("PythonExamples.org")
window.geometry("300x200")

def button_click():
    window.destroy()

# Create a button
button = tk.Button(window, text="Close window", command=button_click)
button.pack()

# Run the application
window.mainloop()

Output

In Windows

In MacOS

If you press Close window button, the window.destroy() method is called, and the window is closed.
