We’ve added the autopep8 hook to our `.pre-commit-config.yaml` to enforce a consistent Python style. To verify its behavior without touching every file at once, we’re applying it in-place to depth_camera.launch.py for now because the large number of impacted files there are. The follow-up PR will run autopep8 accross the entire codebase once this initial change passes CI. ref: https://github.com/hhatto/autopep8
