Fix remaining Flake8 whitespace issues

[thopre]

Summary

Fix the following Flake8 errors:

• E211 (whitespace before opening parenthesis)
• E241 (multiple spaces after comma)

[tnfchris]

This seems rather random compared with D94789... so the spacing rule isn't consistent for assignments?

I'm not too familiar with the rules but I fail to see the inconsistency since this change does not modify any space around assignment, only spaces before parenthesis.

Oh indeed. I for some reason thought it changed the =.

LGTM.
