Untested code snippets:

class Task(threading.Thread):
    def __init__(self, queue):
        threading.Thread.__init__(self)
        self.queue = queue

    def run(self):
        # do stuff like write to self.queue
        ...


In the parent code:

import Queue
q = Queue.Queue()
task = Task(q)
task.start()
# do stuff like read from "q"
...

In other words, pass the Queue object you want to use in to the
Thread when you create it.  There are some alternatives, but this
one generally works best.
