Creating and executing a periodic task in Python with no additionnal module (without Celery)

periodic.py

# Only dependency needed
import threading

# Dependency for the task
import datetime
import time

# Function wrapper 
def periodic_task(interval, times = -1):
    def outer_wrap(function):
        def wrap(*args, **kwargs):
            stop = threading.Event()
            def inner_wrap():
                i = 0
                while i != times and not stop.isSet():
                    stop.wait(interval)
                    function(*args, **kwargs)
                    i += 1

            t = threading.Timer(0, inner_wrap)
            t.daemon = True
            t.start()
            return stop
        return wrap
    return outer_wrap


@periodic_task(10)
def my_periodic_task():
    # This function is executed every 10 seconds
    print("I am executed at {}".format(datetime.datetime.now()))

# Call the function once to launch the periodic system
my_periodic_task()
# This task will run while the program is alive, so for testing purpose we're just going to sleep.
time.sleep(500)

Worked for me brother!

I'm glad it did!

It helped me. One correction is that you're missing a closing brace in line no 31 :)

Updated ;) Thanks
