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

[Kevin O'Gorman]

I no longer have the directory in which I did this trial.  However, trying
again in an empty directory, the sample works fine with 3.5.

  Example of Queue from documentation fails

  New

Bug description:
  Reading https://docs.python.org/3.5/library/multiprocessing.html
  #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.
