How to Execute Code Regularly at Specified Intervals

In Python, it is possible to execute a certain code sequence at predetermined intervals, such as printing a message or updating a file. One method to achieve this is through the use of the threading module's Timer object.

The threading.Timer class in Python allows for the creation of scheduled tasks that can be executed at a specified interval. To use it, you can create a function containing the code you want to execute and call the start() method of the Timer object to schedule it.

Here's an example that prints "Hello, World!" every 5 seconds:

import threading

def printit():
  threading.Timer(5.0, printit).start()
  print("Hello, World!")

printit()

This code creates a new thread that runs the printit() function every 5 seconds. The thread starts running immediately, and the main code continues execution without waiting for the thread to complete.

This approach can be particularly useful when you need to update data or perform background tasks at regular intervals without blocking the main program flow.
