I'm currently trying to get my program to process several jobs from several classes and I can't get it to actually perform the process() function. This is based on one of the topics found online.
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")
This returns as expected:
Starting Thread-1
Starting Thread-2
Starting Thread-3
Thread-1 processing <bound method myclass1.process of <myclass1.myclass1 object at 0x7fc163542e10>>
Thread-2 processing <bound method myclass2.process of <myclass2.myclass2 object at 0x7fc163542dd8>>
Thread-3 processing <bound method myclass3.process of <myclass3.myclass3 object at 0x7fc163542a20>>
Thread-1 processing <bound method myclass4.process of <myclass4.myclass4 object at 0x7fc16354e080>>
Thread-3 processing <bound method myclass5.process of <myclass5.myclass5 object at 0x7fc16354e438>>
Exiting Thread-1
Exiting Thread-3
Exiting Thread-2
Exiting Main Thread
I currently use Thread(target=myclassX.process) but now it's different... How could I modify my program to actually make it perform the process() function for each class instead of just adding it as a bound method in the queue?
