在类线程Python之间发送消息

有没有人知道如何在不使用全局变量的情况下在此代码中从threadOne向threadTwo发送变量(或获取变量)?如果没有,我将如何操作全局变量?只需在两个类之前定义它并在run函数中使用全局定义?

import threading

print "Press Escape to Quit"

class threadOne(threading.Thread): #I don't understand this or the next line
    def run(self):
        setup()

    def setup():
        print 'hello world - this is threadOne'


class threadTwo(threading.Thread):
    def run(self):
        print 'ran'

threadOne().start()
threadTwo().start()

谢谢

您可以使用queues以线程安全的方式在线程之间发送消息.

def worker():
    while True:
        item = q.get()
        do_work(item)
        q.task_done()

q = Queue()
for i in range(num_worker_threads):
     t = Thread(target=worker)
     t.daemon = True
     t.start()

for item in source():
    q.put(item)

q.join()       # block until all tasks are done
