Queue模塊允許創建指定長度的隊列. 下面是Queue模塊的常用方法:

get():刪除并返回隊列中的一個項目

put(): 添加項目到隊列

qsize() : 返回隊列中元素的個數
empty(): 隊列為空返回True否則返回False

full(): 隊列已滿返回True，負責返回False

#!/usr/bin/python

import Queue
import threading
import time
exitFlag = 0
class myThread (threading.Thread):
    def init(self, threadID, name, q):
        threading.Thread.init(self)
        self.threadID = threadID
        self.name = name
        self.q = q
    def run(self):
        print "Starting " + self.name
        process_data(self.name, self.q)
        print "Exiting " + self.name
def process_data(threadName, q):
    while not exitFlag:
        queueLock.acquire()
        if not workQueue.empty():
            data = q.get()
            queueLock.release()
            print "%s processing %s" % (threadName, data)
        else:
            queueLock.release()
        time.sleep(1)
threadList = ["Thread-1", "Thread-2", "Thread-3"]
nameList = ["One", "Two", "Three", "Four", "Five"]
queueLock = threading.Lock()
workQueue = Queue.Queue(10)
threads = []
threadID = 1
Create new threads
for tName in threadList:
    thread = myThread(threadID, tName, workQueue)
    thread.start()
    threads.append(thread)
    threadID += 1
Fill the queue
queueLock.acquire()
for word in nameList:
    workQueue.put(word)
queueLock.release()
Wait for queue to empty
while not workQueue.empty():
    pass
Notify threads it's time to exit
exitFlag = 1
Wait for all threads to complete
for t in threads:
    t.join()
print "Exiting Main Thread"
 </pre> 

 輸出結果如下：
Starting Thread-1
Starting Thread-2
Starting Thread-3
Thread-1 processing One
Thread-2 processing Two
Thread-3 processing Three
Thread-1 processing Four
Thread-2 processing Five
Exiting Thread-3
Exiting Thread-1
Exiting Thread-2
Exiting Main Thread
