具有多个目标函数的Python线程

我目前正试图让我的程序处理来自几个类的几个作业,但我无法让它实际执行process()函数。这是基于在网上找到的一个主题。在

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)
            myThread.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 ("{0} processing {1}".format(threadName, data))
                else:
                    queueLock.release()
                time.sleep(1)

threadList = ["Thread-1", "Thread-2", "Thread-3"]
nameList = [myclass1.process, myclass2.process, myclass3.process, myclass5.process, myclass6.process]
queueLock = threading.Lock()
workQueue = queue.Queue()
threads = []
threadID = 1
exitFlag = 0
# 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")    

这将按预期返回:

^{pr2}$

我目前使用线程(目标=myclassX.流程)但现在不同了。。。 我如何修改我的程序,使其实际为每个类执行process()函数,而不是将其作为绑定方法添加到队列中?在
