Ok, I figured out what was wrong with my code.

Since asyncio.Queue.put() is a coroutine, I should have wrapped those
with asyncio.Task in order for them to start executing.

Therefore, this works;

    q =3D asyncio.Queue()
    loop =3D asyncio.get_event_loop()

    for i in range(num_coroutines):  # start 10 tasks
        tasks.append(asyncio.Task(print_status_code(q)))

    for loc in soup.find_all('loc'):
        asyncio.Task(q.put(loc.string))

    for i in range(num_coroutines):  # Put poison pil.
        asyncio.Task(q.put(None))

    print("%i items in queue" % q.qsize())

    loop.run_until_complete(asyncio.wait(tasks))
