However, there are situations in which you might want to be able to stop a thread, so let me show you how to do it:

# stop.pyimport threadingfrom time import sleepclass Fibo(threading.Thread):    def __init__(self, *a, **kwa):        super().__init__(*a, **kwa)        self._running = True    def stop(self):        self._running = False    def run(self):        a, b = 0, 1        while self._running:            print(a, end=' ')            a, b = b, a + b            sleep(0.07)        print()fibo = Fibo()fibo.start()sleep(1)fibo.stop()fibo.join()print('All done.')

For this example, we use a Fibonacci ...
