black

A Python auto code formatter. More information: https://github.com/psf/black.

  • Auto-format a file or entire directory:

black {{path/to/file_or_directory}}

  • Format the code passed in as a string:

black -c "{{code}}"

  • Output the changes that would be applied for each file:

black --diff {{path/to/file_or_directory}}

  • Perform a dry run (print what would be done without actually doing it):

black --check {{path/to/file_or_directory}}

  • Auto-format a file or directory emitting exclusively error messages to stderr:

black --quiet {{path/to/file_or_directory}}

  • Auto-format a file or directory without replacing single quotes with double quotes (adoption helper, avoid using this for new projects):

black --skip-string-normalization {{path/to/file_or_directory}}
