How to add script delay in multithreading?

Question

Python

There is a script which is executed in a flow. It is necessary that after the execution of all active threads - the script is turned off for the N-th number of seconds, and then calls the function to restart, i.e. create a recursion. I tried to do this after the for loop, but the time.sleep function is called while the thread is still running. How can a function be called after all active threads have terminated?

import time
from threading import Thread


class MyThread(Thread):
    def __init__(self, name):
        Thread.__init__(self)
        self.name = name

    def run(self):
        msg = "%s is running" % self.name
        print(msg)


def create_threads():
    for i in range(5):
        name = "Thread #%s" % (i + 1)
        my_thread = MyThread(name)
        my_thread.start()

time.sleep(5)
create_threads()

if __name__ == "__main__":
    create_threads()

Wait for them to complete by calling the join method of each of the threads, or use one of the synchronization primitives for the same purpose.
