Sean McGinnis d601415259 Clean up W503 and E402 pep8 errors
pycodestyle 2.40 and later enforce these rules that were not previously
enforced. Rather than just skipping them, this cleans up the trivial
instances of these violations.

This does also include some other updates that were not triggering errors
in an attempt to keep some of the style consistent.
