Black is a opinionated python code formatter.
The mozlint integration of black can be run using mach:
$ mach lint --linter black <file paths>
Alternatively, omit the --linter black and run all configured linters, which will include black.
To enable black on new directory, add the path to the include section in the black.yml <tools/lint/black.yml> file.
The black linter provides a --fix option.
