How can I execute code at specific intervals in Python?

Implementing Recurring Code Execution at Specified Intervals

One may face the need to execute specific code segments at fixed intervals. This could involve tasks such as printing messages, updating files, or performing periodic checks.

Using Threading for Code Recurrence

In Python, one can leverage the threading module and its Timer class to achieve this. Here's an example:

import threading

def custom_task():
  # Define the code to be executed repeatedly
  # (replace "Hello, World!" with your desired task)
  print("Hello, World!")

  # Set up recursion by creating a new timer object
  threading.Timer(5.0, custom_task).start()

# Start the initial execution thread
custom_task()

# Continue with other code tasks

By utilizing threading, this code runs your custom task every 5 seconds in the background while allowing other code to execute simultaneously.

Understanding Timer Objects

The Timer object from the threading module offers additional functionalities:

• Timer(interval, function): Creates a new timer to execute function after the specified interval.
• start(): Starts the timer.
• cancel(): Cancels the timer before it expires or executes.
• is_alive(): Returns True if the timer is still running.
