Nit: We usually rely on PEP-8 for Python style guide. We have a style checker
for Python (https://hg.adblockplus.org/codingtools/file/tip/flake8-eyeo). It
would be cool to run the check on the whole file (and other Python files here),
but at least I know that lines longer than 80 cars would trigger a warning. So
maybe put parameters on separate lines here?

Thanks for letting me know.
Should we use Chromium python code style (original repo) or eyeo?
