You have to call the join() method of the thread object from another
thread. This will terminate the thread and free its resources. This is
usually the task of the parent thread which usually does something
like:
t = MyTread(...)
t.start()
# do your own stuff, then before quitting
t.join() # Note that this waits until t is terminated

Yes. You can try yourself:
>>> import threading
>>> class MyThread(threading.Thread):
def __init__(self): threading.Thread.__init__(self)
def stop(self): self._stop = True
def run(self):
self._stop= False
while self._stop == False:
import time
time.sleep(0.1)
>>> t = MyThread()
>>> t.start()
>>> t.isAlive()
True
>>> t.isAlive()
False
>>> t.join()
>>> t.isAlive()
False
