It's really good that you fixed the PEP8 violation, but in doing so you accidentally violated [PEP257 - the docstring convention](http://www.python.org/dev/peps/pep-0257/). The fist line of a method docstring should be a summary of what the method does, and that summary shouldn't be longer than 1 line. If you need more text to explain, then you can do it after the summary. Check out the link, the pep has quite a few examples and explanations. You can run the tool ``pep257`` to test that your code follows this convention. ``pip install pep257`` to get it.
