代码如下:
class Producer(threading.Thread):
def __init__(self, threadname, queue):
threading.Thread.__init__(self, name = threadname)
self.sharedata = queue
def run(self):
for i in range(20):
print self.getName(),'adding',i,'to queue'
self.sharedata.put(i)
time.sleep(random.randrange(10)/10.0)
print self.getName(),'Finished'
# Consumer thread
class Consumer(threading.Thread):
def __init__(self, threadname, queue):
threading.Thread.__init__(self, name = threadname)
self.sharedata = queue
def run(self):
for i in range(20):
print self.getName(),'got a value:',self.sharedata.get()
time.sleep(random.randrange(10)/10.0)
print self.getName(),'Finished'
# Main thread
def main():
queue = Queue()
producer = Producer('Producer', queue)
consumer = Consumer('Consumer', queue)
print 'Starting threads ...'
producer.start()
consumer.start()
producer.join()
consumer.join()
print 'All threads have terminated.'
if __name__ == '__main__':
main()
