How to Execute Functions Periodically in Windows?

Executing Periodic Actions in Windows

Executing a specific function at regular intervals is a common task in programming. In Windows, you need a way to schedule the function's execution repeatedly.

Method:

To execute a function (foo()) every 10 seconds in Windows, a simple and effective approach is to use the Timer class. This class allows you to set a delay and a callback function to be executed when the delay expires.

Implementation:

Within the foo() function, you can create a new Timer object with a delay of 10 seconds and the foo() function as the callback. This Timer will automatically call foo() after the specified interval.

import time, threading

def foo():
    # Do the task
    print(time.ctime())

    # Schedule the next execution
    threading.Timer(10, foo).start()

foo()

Explanation:

• Creating the Timer in foo() ensures that it will be called repeatedly, as long as the foo() function is being executed.
• The Timer creates a separate thread to call foo(), allowing you to continue performing other tasks without blocking the main thread.
