lint goal runs both dedicated linters and any formatters in check-only mode:
See here for how to opt in to specific formatters and linters, along with how to configure them.
Benefit of Pants: runs linters in parallel
Pants will run all activated linters at the same time for improved performance. As explained at Python linters and formatters, Pants also uses some other techniques to improve concurrency, such as dynamically setting the
--jobsoption for linters that have it.
Benefit of Pants: lint Python 2-only and Python 3-only code at the same time
Bandit, Flake8, and Pylint depend on which Python interpreter the tool is run with. Normally, if your project has some Python 2-only files and some Python 3-only files, you would not be able to run the linter in a single command because it would fail to parse your code.
Instead, Pants will do the right thing when you run
pants lint ::. Pants will group your targets based on their interpreter constraints, and run all the Python 2 targets together and all the Python 3 targets together.
