In Tkinter, you can prevent a window from being resized by using the resizable method and passing False for both width and height parameters. Here is an example:

Code:

import tkinter as tk

root = tk.Tk()
root.geometry('200x200')
root.resizable(width=False, height=False)
root.mainloop()


In this code, root.resizable(width=False, height=False) makes the window non-resizable123. This means the user cannot change the dimensions of the window, and it also disables the maximize button1. You can easily implement this into your code1. Please note that this information is based on the current understanding and may change as more research is conducted.
