python: Resolve some indentation warnings.

This patch resolves the following warnings from flake8:

 E111 indentation is not a multiple of four
 E112 expected an indented block
 E113 unexpected indentation

It's critical to have correct indentation in Python code, so it seemed
worth enabling these warnings.
