black

Format Python code automatically. More information: https://black.readthedocs.io/en/stable/usage_and_configuration/the_basics.html.

• Auto-format a file or entire directory:

black {{path/to/file_or_directory}}

• Format the [c]ode passed in as a string:

black -c "{{code}}"

• Show whether a file or a directory would have changes made to them if they were to be formatted:

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

• Show changes that would be made to a file or a directory without performing them (dry-run):

black --diff {{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}}
