Why does the instance need to be recreated when restarting a thread?

Question

Imagine the following classes:

Class Object(threading.Thread):
    # some initialisation blabla
    def run(self):
        while True:
            # do somet         


        

Answer 1

I believe, that has to do with how Thread class is implemented. It wraps a real OS thread, so that restarting the thread would actually change its identity, which might be confusing.

A better way to deal with threads is actually through target functions/callables:

class Worker(object):
    """ Implements the logic to be run in separate threads """
    def __call__(self):
        #  do useful stuff and change the state

class Supervisor():
    def run(self, worker):
        thr = None
        while True:
            if not thr or not thr.is_alive():
                thr = Thread(target=worker)
                thr.daemon = True
                thr.start()
            thr.join(1)  # give it some time
