Does pycodestyle work with Python 2.7? Our automation is still primarily Python 2.7. Although all scripts should be Python 3 compliant now, we still aren't running things that way in most places. I think our oldest supported OS is now Mojave, so we probably aren't far from a post-Python 2 world in WebKit, but I haven't had any conversations about that it the last few weeks. 1672882 3 mcatanzaro 2020-07-19 06:54:43 -0700 (In reply to Jonathan Bedard from comment #2) > Does pycodestyle work with Python 2.7?
