black - uncompromising Python code formatter

Options:-c,--codeTEXT
                     Format the code passed in as a string.

              -l,--line-lengthINTEGER
                     How many characters per line to allow.  [default: 88]

              -t,--target-version[py27|py33|py34|py35|py36|py37|py38|py39]
                     Python  versions  that  should  be  supported  by  Black's output. [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.

              -C, --skip-magic-trailing-comma
                     Don't use trailing commas as a reason to split lines.

              --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.

              --color/--no-colorShowcoloreddiff.Onlyapplieswhen--diff is given.

              --fast/--safeIf--fastgiven,skiptemporarysanity
                     checks. [default: --safe]

              --includeTEXT
                     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?$]

              --excludeTEXT
                     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)/]

              --extend-excludeTEXT
                     Like  --exclude,  but  adds  additional  files and directories on top of the excluded ones.
                     (Useful if you simply want to add to the default)

              --force-excludeTEXT
                     Like --exclude, but files and directories matching this regex will be  excluded  even  when
                     they are passed explicitly as arguments.

              --stdin-filenameTEXT
                     The  name of the file when passing it through stdin. Useful to make sure Black will respect
                     --force-exclude option on some editors that rely on using stdin.

              -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.

              --configFILE
                     Read configuration from PATH.

              -h, --help
                     Show this message and exit.
