Is the python thread method different in IDLE and pycharm?

In fact, I run and debug these codes as below in both IDLE(Python 3.5.2 shell ) and Pycharm Community Edition 2017.2. But when I run the code many times, I found there are some questions confused me. The code run in pycharm generates this result:

• Thread-3 processing One Thread-1 processing Two Thread-3 processing Three Thread-2 processing Four Thread-3 processing Five Thread-1 processing Six Thread-2 processing Seven Thread-1 processing Eight

The code run in pycharm generates this result:

• Thread-1 processing One Thread-2 processing Two Thread-3 processing Three Thread-1 processing Four Thread-2 processing Five Thread-3 processing Six Thread-1 processing Seven Thread-2 processing Eight

As you can see, "1 3 2 3 1 2 1" and "2 3 1 2 3 1 2". I run many times and find this. So I just want to know, why the thread method is different in different IDE? And could you please tell me some good directions for learning thread in Python3?

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("Open Thread：" + self.name)
        process_data(self.name, self.q)
        print("Exit Thread：" + self.name)


def process_data(threadName, q):
    while not exitFlag:

        queueLock.acquire()
        if not workQueue.empty():
            data = q.get()
            print("%s processing %s" % (threadName, data))
            queueLock.release()
        else:
            queueLock.release()
        time.sleep(1)


threadList = ["Thread-1", "Thread-2", "Thread-3"]
nameList = ["One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"]
queueLock = threading.Lock()
workQueue = queue.Queue(10)
threads = []
threadID = 1

for tname in threadList:
    thread = myThread(threadID, tname, workQueue)
    thread.start()
    threads.append(thread)
    threadID += 1

queueLock.acquire()
for word in nameList:
    #print(workQueue.empty())
    workQueue.put(word)
    #time.sleep(1)
queueLock.release()

while not workQueue.empty():
    pass

exitFlag = 1

for t in threads:
    t.join()

print("Exit Main Thread")
