How can I prevent a window from being resized with tkinter?

Question

I have a program which creates a window where a message is displayed according to a check box.

How can I make the window size constant when the message is displayed

Answer 1

This is a variant of an existing solution already provided above:

import tkinter as tk

root = tk.Tk()
root.resizable(0, 0)
root.mainloop()

The advantage is that you type less.
