Set Up Code Linting #2
Description
Similar to #1 , it is useful to additionally set up code-linting to ensure that the system code conforms to a style guideline (PEP8). YAPF is a useful tool to do so as it can format files to conform to a guideline and check whether files conform to a guideline (as can pep8ify and autopep8), but will additionally format code to make it look nice.
Style checks can be added to the Travis Build Job to return errors if contributors have not linted their code.
Pre-commit hooks can also be created (but must then be set up by contributors individually) to automate code linting before commits. A note on this is that users must then manually stage changes applied by YAPF.
