A Python auto code formatter.
Auto-format a file or directory without replacing single quotes with double quotes (adoption helper, avoid using this for new projects)
black is the uncompromising Python code formatter.
black is the uncompromising Python code formatter. By using it, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters.

-l, --line-length INTEGER How many characters per line to allow. [default: 88] --py36 Allow using Python 3.6-only syntax on all input files. This will put trailing commas in function signatures and calls also after *args and **kwargs. [default: per-file auto-detection] --pyi Format all input files like typing stubs regardless of file extension (useful when piping source on standard input). -S, --skip-string-normalization Don't normalize string quotes or prefixes. --check Don't write the files back, just return the status. Return code 0 means nothing would change. Return code 1 means some files would be reformatted. Return code 123 means there was an internal error. --diff Don't write the files back, just output a diff for each file on stdout. --fast / --safe If --fast given, skip temporary sanity checks. [default: --safe] --include TEXT A regular expression that matches files and directories that should be included on recursive searches. An empty value means all files are included regardless of the name. Use forward slashes for directories on all platforms (Windows, too). Exclusions are calculated first, inclusions later. [default: \.pyi?$] --exclude TEXT A regular expression that matches files and directories that should be excluded on recursive searches. An empty value means no paths are excluded. Use forward slashes for directories on all platforms (Windows, too). Exclusions are calculated first, inclusions later. [default: /(\.git|\.hg|\.mypy_cache| \.tox|\.venv|_build|buck-out|build|dist)/] -q, --quiet Don't emit non-error messages to stderr. Errors are still emitted, silence those with 2>/dev/null. -v, --verbose Also emit messages to stderr about files that were not changed or were ignored due to --exclude=. --version Show the version and exit. --config FILE Read configuration from PATH. -h, --help Show this message and exit.
