There are some style changes that need to get fixed, but other than that it should be good to go.
To check the code style you need pycodestyle, pydocstyle, and pylint.
To install them: pip install pycodestyle pydocstyle pylint
Make sure all 3 of these commands do not output any errors:
python -m pycodestylepython -m pydocstylepython -m pylint
The continuous integration checker will also ensure that these pass.
