Writing and Running Doctests: ValueError when just running python -m doctest

I was following along with "Writing and Running Doctests" in my local Terminal and when I ran python -m doctest dd_game.py, I got these errors that weren't pointing to the file I was testing.

When I ran it again without dd_game.py I was getting similar errors. Do I need to reinstall Python or something?

python -m doctest
Traceback (most recent call last):
  File "/Users/atotalpirate/Sites/_app/python/logging.py", line 4, in <module>
    [1, 2, 3].remove(4)
ValueError: list.remove(x): x not in list

During handling of the above exception, another exception occurred:

Hello Jimmy,

the track cleary states where the error came from: 

/Users/atotalpirate/Sites/_app/python/logging.py", line 4
[1, 2, 3].remove(4)
ValueError: list.remove(x): x not in list

There also seems to be an error with your logging which is reported at the very bottom: You should not give a reserved name such as 'logging.py' to your own files: the logging python module is not recognized here, since Python takes your file as an overwrite of the build in logging module.

File "/Users/atotalpirate/Sites/_app/python/logging.py", line 6, in <module>
    logging.error("tried to remove an invalid value")
AttributeError: module 'logging' has no attribute 'error'```

I was also in the wrong virtualenv.

Shame

Thanks for your answer!
