Running a method as a background thread with sleep in Python

    import threading
    import time


    class ThreadingExample(object):
        """ Threading example class
        The run() method will be started and it will run in the background
        until the application exits.
        """

        def __init__(self, interval=1):
            """ Constructor
            :type interval: int
            :param interval: Check interval, in seconds
            """
            self.interval = interval

            thread = threading.Thread(target=self.run, args=())
            thread.daemon = True                            # Daemonize thread
            thread.start()                                  # Start the execution

        def run(self):
            """ Method that runs forever """
            while True:
                # Do something
                print('Doing something imporant in the background')

                time.sleep(self.interval)

    example = ThreadingExample()
    time.sleep(3)
    print('Checkpoint')
    time.sleep(2)
    print('Bye')
