Question

I want to know what the most recently enqueued item is in a queue. how do I find this out?

In other words, how to find the last item that a queue will dequeue ( or the most recently enqueued item)

Answer 1

Im not entirely sure what you are trying to achieve here, but the following might work, just check that the queue is not empty.

>>> from Queue import Queue
>>> q = Queue()    
>>> _ = [q.put(index) for index in xrange(2, 10)]
>>> if not q.empty():
...    q.queue[-1]
9
>>> 

Im assuming that you are using python’s own Queue object, which I would recommend since its thread safe 🙂
