Can you please run tools/distrib/yapf_code.sh?

Out of curiosity, since I've seen at least one other PR from you, are you vendoring gRPC for a distro or something?

Yes, I am maintaining the Arch Linux package.

The script doesn't work as-is on Arch since python3 doesn't exist (python 3 is python while python 2 is python2) and also the virtualenv module is not present but the venv module should be used instead (built into python since 3.3) with the command python -m venv $VIRTUALENV.

Anyway I ran it after fixing it but it's also changing the format of src/python/grpcio_tests/tests_aio/benchmark/worker_servicer.py.

I force pushed the amended commit with the fixed setup.py and ignored the changes in other files.

Nice! I thought your name looked familiar. I use your package on my personal machine at home. I've commented in the past how the Arch package somehow gets published before we get our package up on PyPi.

Unrelated flake.
