[Bug 1628763] Re: Example of Queue from documentation fails

[Kevin O'Gorman]

Oops.  I did locate the directory on a backup.  As you supposed, I had
created queue.py initially to do the test.  I re-ran it as 'q.py' to see if
that helped, but did not delete the original.  So you were right -- name
conflict.

  #exchanging-objects-between-processes, I have copy-pasted the code
  into a file.  Running it with python3 fails thus:

  Traceback (most recent call last):
    File "q.py", line 7, in <module>
      q = Queue()
    File "/usr/lib/python3.5/multiprocessing/context.py", line 100, in Queue
      from .queues import Queue
    File "/usr/lib/python3.5/multiprocessing/queues.py", line 20, in <module>
      from queue import Empty, Full
  ImportError: cannot import name 'Empty'

  
  I will attach the actual code file.
