How to Execute a Function Every 10 Seconds in Windows Using a Timer Object?

Executing Periodic Actions

Executing specific functions at regular intervals is a common task in programming. One such scenario is the requirement to execute a function called foo() every 10 seconds. Various programming environments offer different mechanisms to achieve this repetition.

In Windows, one effective approach is to utilize a Timer object. This object creates a new thread that executes the desired function periodically. After completing the function, the Timer object reschedules itself to run the function again after a specified interval.

For instance, consider the following code snippet:

import time, threading
def foo():
    print(time.ctime())
    threading.Timer(10, foo).start()

foo()

In this code, the foo() function is called initially. Inside the function, the time.ctime() function is used to print the current time. Subsequently, a Timer object is created that will call the foo() function again after 10 seconds. This Timer object starts a new thread, allowing the program to continue executing other tasks without blocking.

Output:

Thu Dec 22 14:46:08 2011
Thu Dec 22 14:46:18 2011
Thu Dec 22 14:46:28 2011
Thu Dec 22 14:46:38 2011

This demonstrates how to create a simple program in Windows that executes a specified function at a specified interval using the Timer object. This technique is particularly useful for scheduling periodic tasks or creating timed events.
