Let's take a simple example and see how to start and stop an infinite loop.Steps −Import the required libraries and create an instance of tkinter frame.Set the size of the frame using win.geometry method.Next, create a user-defined function "infinite_loop" which will call itself recursively and print a statement on the window.Define two more user-defined functions, start() and stop(), to control the infinite_loop. Define a global variable "condition". Inside start(), ...
