class mythread(threading.Thread):
def __init__(self, num, threadname):
 threading.Thread.__init__(self, name = threadname)
 self.num = num
#self.daemon = True
def run(self):
 time.sleep(self.num)
print(self.num)
t1 = mythread(1,'t1')
t2 = mythread(5,'t2')
t2.daemon =True
#t2.setDaemon(False)
print(t1.daemon)
print(t2.daemon)
t1.start()
t2.start()
