you can do a check by hasattr()
Yes, a Queue object has a queue attribute:
>>> import Queue
>>> q = Queue.Queue()
>>> q.queue
deque([])
But you shouldn't use it. It's part of the implementation of Queue, not
meant for you to use directly. In particular, if you use it directly,
you are skipping all synchronization, which is the main reason to use a
Queue in the first place.
It should have been named "_queue". We'll add that to the list of PEP-8
violations in the Queue module! :)
