生产者-消费者模型-线程安全队列Queue

#python3
#product new data into the queue
#comsume data from the queue

简单案例：

#!/usr/bin/python
import time, threading,Queue
#class to do sth
class Comsumer(threading.Thread):
def __init__(self,queue):
　　threading.Thread.__init__(self)
　　self.queue = queue
def run(self):
　　while True:
　　　　msg = self.queue.get()
　　　　if msg == 'quit':
　　　　　　break
　　　　print 'msg is : {0}'.format(msg)
　　　　time.sleep(1)
　　print 'good bye'

def producer():
　　queue = Queue.Queue()
　　worker = Comsumer(queue)
　　worker.start()# 开启消费者线程

　　for i in range(5):
　　　　queue.put('queue-{0}'.format(i))
　　queue.put('quit')
　　worker.join() #不是queue.join()

if __name__ == '__main__':
　　producer()
