Style and linting

Python

Follow the Python Style Guide (PSG) as formulated in PEP-8: http://www.python.org/dev/peps/pep-0008/
Use pylint to lint code.

The critical points are:

Use spaces; never use tabs
4 space indentation
79 character line limit
Variables, functions and methods should be lower_case_with_underscores
Classes are TitleCase

And other preferences:

Use ' and not " as the quote character by default
When writing a method, consider if it is really a method (needs self) or if it would be better as a utility function
When writing a @classmethod, consider if it really needs the class (needs cls) or it would be better as a utility function or factory class

Python Version

As a rule, all Python code should be written to support Python 3.7 or greater.
