 ## Coding conventions, code quality
  
 - Respect [PEP8](https://www.python.org/dev/peps/pep-0008/) conventions.
 - Add just the "right" amount of comments. Try to write auto-documented code with very explicit variable names.
 - If you introduce new functionality or fix a bug, document it in the docstring or with code comments.
