[files ...]
Sort Python import definitions alphabetically within logical sections. Run with no arguments to
see a quick start guide, otherwise, one or more files/directories/stdin must be provided. Use `-`
as the first argument to represent stdin. Use --interactive to use the pre 5.0.0 interactive
behavior. If you've used isort 4 but are new to isort 5, see the upgrading guide:
https://isort.readthedocs.io/en/latest/upgrade_guides/5.0.0.html
general options:
-h, --help show this help message and exit
-V, --version Displays the currently installed version of isort.
--vn, --version-number
Returns just the current version number without the logo
-v, --verbose Shows verbose output, such as when files are skipped or when a check is
successful.
--only-modified, --om
Suppresses verbose output for non-modified files.
--dedup-headings Tells isort to only show an identical custom import heading comment once,
even if there are multiple sections with the comment set.
-q, --quiet Shows extra quiet output, only errors are outputted.
-d, --stdout Force resulting output to stdout, instead of in-place.
--overwrite-in-place Tells isort to overwrite in place using the same file handle. Comes at a
performance and memory usage penalty over its standard approach but
ensures all file flags and modes stay unchanged.
--show-config See isort's determined config, as well as sources of config options.
--show-files See the files isort will be run against with the current config options.
--df, --diff Prints a diff of all the changes isort would make to a file, instead of
changing it in place
-c, --check-only, --check
Checks the file for unsorted / unformatted imports and prints them to the
command line without modifying the file. Returns 0 when nothing would
change and returns 1 when the file would be reformatted.
--ws, --ignore-whitespace
Tells isort to ignore whitespace differences when --check-only is being
used.
--sp SETTINGS_PATH, --settings-path SETTINGS_PATH, --settings-file SETTINGS_PATH, --settings SETTINGS_PATH
Explicitly set the settings path or file instead of auto determining based
on file location.
--cr CONFIG_ROOT, --config-root CONFIG_ROOT
Explicitly set the config root for resolving all configs. When used with
the --resolve-all-configs flag, isort will look at all sub-folders in this
config root to resolve config files and sort files based on the closest
available config(if any)
--resolve-all-configs
Tells isort to resolve the configs for all sub-directories and sort files
in terms of its closest config files.
--profile PROFILE Base profile type to use for configuration. Profiles include: black,
django, pycharm, google, open_stack, plone, attrs, hug, wemake, appnexus.
As well as any shared profiles.
-j [JOBS], --jobs [JOBS]
Number of files to process in parallel. Negative value means use number of
CPUs.
--ac, --atomic Ensures the output doesn't save if the resulting file contains syntax
errors.
--interactive Tells isort to apply changes interactively.
--format-error FORMAT_ERROR
Override the format used to print errors.
--format-success FORMAT_SUCCESS
Override the format used to print success.
--srx, --sort-reexports
Automatically sort all re-exports (module level __all__ collections)
target options:
files One or more Python source files that need their imports sorted.
--filter-files Tells isort to filter files even when they are explicitly passed in as
part of the CLI command.
-s SKIP, --skip SKIP Files that isort should skip over. If you want to skip multiple files you
should specify twice: --skip file1 --skip file2. Values can be file names,
directory names or file paths. To skip all files in a nested path use
--skip-glob.
--extend-skip EXTEND_SKIP
Extends --skip to add additional files that isort should skip over. If you
want to skip multiple files you should specify twice: --skip file1 --skip
file2. Values can be file names, directory names or file paths. To skip
all files in a nested path use --skip-glob.
--sg SKIP_GLOB, --skip-glob SKIP_GLOB
Files that isort should skip over.
--extend-skip-glob EXTEND_SKIP_GLOB
Additional files that isort should skip over (extending --skip-glob).
--gitignore, --skip-gitignore
Treat project as a git repository and ignore files listed in .gitignore.
NOTE: This requires git to be installed and accessible from the same shell
as isort.
--ext SUPPORTED_EXTENSIONS, --extension SUPPORTED_EXTENSIONS, --supported-extension SUPPORTED_EXTENSIONS
Specifies what extensions isort can be run against.
--blocked-extension BLOCKED_EXTENSIONS
Specifies what extensions isort can never be run against.
--dont-follow-links Tells isort not to follow symlinks that are encountered when running
recursively.
--filename FILENAME Provide the filename associated with a stream.
--allow-root Tells isort not to treat / specially, allowing it to be run against the
root dir.
general output options:
-a ADD_IMPORTS, --add-import ADD_IMPORTS
Adds the specified import line to all files, automatically determining
correct placement.
--append, --append-only
Only adds the imports specified in --add-import if the file contains
existing imports.
--af, --force-adds Forces import adds even if the original file is empty.
--rm REMOVE_IMPORTS, --remove-import REMOVE_IMPORTS
Removes the specified import from all files.
--float-to-top Causes all non-indented imports to float to the top of the file having its
imports sorted (immediately below the top of file comment). This can be an
excellent shortcut for collecting imports every once in a while when you
place them in the middle of a file to avoid context switching. *NOTE*: It
currently doesn't work with cimports and introduces some extra over-head
and a performance penalty.
--dont-float-to-top Forces --float-to-top setting off. See --float-to-top for more
information.
--ca, --combine-as Combines as imports on the same line.
--cs, --combine-star Ensures that if a star import is present, nothing else is imported from
that namespace.
-e, --balanced Balances wrapping to produce the most consistent line length possible
--ff, --from-first Switches the typical ordering preference, showing from imports first then
straight ones.
--fgw [FORCE_GRID_WRAP], --force-grid-wrap [FORCE_GRID_WRAP]
Force number of from imports (defaults to 2 when passed as CLI flag
without value) to be grid wrapped regardless of line length. If 0 is
passed in (the global default) only line length is considered.
--fs FORCED_SEPARATE, --forced-separate FORCED_SEPARATE
Force specified sub modules to show separately. To specify multiple
modules, use the argument multiple times: --forced-separate typing
--forced-separate six.
-i INDENT, --indent INDENT
String to place for indents defaults to " " (4 spaces).
--lbi LINES_BEFORE_IMPORTS, --lines-before-imports LINES_BEFORE_IMPORTS
--lai LINES_AFTER_IMPORTS, --lines-after-imports LINES_AFTER_IMPORTS
--lbt LINES_BETWEEN_TYPES, --lines-between-types LINES_BETWEEN_TYPES
--le LINE_ENDING, --line-ending LINE_ENDING
Forces line endings to the specified value. If not set, values will be
guessed per-file.
--ls, --length-sort Sort imports by their string length.
--lss, --length-sort-straight
Sort straight imports by their string length. Similar to `length_sort` but
applies only to straight imports and doesn't affect from imports.
-m {GRID,VERTICAL,HANGING_INDENT,VERTICAL_HANGING_INDENT,VERTICAL_GRID,VERTICAL_GRID_GROUPED,VERTICAL_GRID_GROUPED_NO_COMMA,NOQA,VERTICAL_HANGING_INDENT_BRACKET,VERTICAL_PREFIX_FROM_MODULE_IMPORT,HANGING_INDENT_WITH_PARENTHESES,BACKSLASH_GRID,0,1,2,3,4,5,6,7,8,9,10,11}, --multi-line {GRID,VERTICAL,HANGING_INDENT,VERTICAL_HANGING_INDENT,VERTICAL_GRID,VERTICAL_GRID_GROUPED,VERTICAL_GRID_GROUPED_NO_COMMA,NOQA,VERTICAL_HANGING_INDENT_BRACKET,VERTICAL_PREFIX_FROM_MODULE_IMPORT,HANGING_INDENT_WITH_PARENTHESES,BACKSLASH_GRID,0,1,2,3,4,5,6,7,8,9,10,11}
Multi line output (0-grid, 1-vertical, 2-hanging, 3-vert-hanging, 4-vert-
grid, 5-vert-grid-grouped, 6-deprecated-alias-for-5, 7-noqa, 8-vertical-
hanging-indent-bracket, 9-vertical-prefix-from-module-import, 10-hanging-
indent-with-parentheses).
-n, --ensure-newline-before-comments
Inserts a blank line before a comment following an import.
--nis, --no-inline-sort
Leaves `from` imports with multiple imports 'as-is' (e.g. `from foo import
a, c ,b`).
--ot, --order-by-type
Order imports by type, which is determined by case, in addition to
alphabetically. **NOTE**: type here refers to the implied type from the
import name capitalization. isort does not do type introspection for the
imports. These "types" are simply: CONSTANT_VARIABLE, CamelCaseClass,
variable_or_function. If your project follows PEP8 or a related coding
standard and has many imports this is a good default, otherwise you likely
will want to turn it off. From the CLI the `--dont-order-by-type` option
will turn this off.
--dt, --dont-order-by-type
Don't order imports by type, which is determined by case, in addition to
alphabetically. **NOTE**: type here refers to the implied type from the
import name capitalization. isort does not do type introspection for the
imports. These "types" are simply: CONSTANT_VARIABLE, CamelCaseClass,
variable_or_function. If your project follows PEP8 or a related coding
standard and has many imports this is a good default. You can turn this on
from the CLI using `--order-by-type`.
--rr, --reverse-relative
Reverse order of relative imports.
--reverse-sort Reverses the ordering of imports.
--sort-order SORT_ORDER
Specify sorting function. Can be built in (natural[default] = force
numbers to be sequential, native = Python's built-in sorted function) or
an installable plugin.
--sl, --force-single-line-imports
Forces all from imports to appear on their own line
--nsl SINGLE_LINE_EXCLUSIONS, --single-line-exclusions SINGLE_LINE_EXCLUSIONS
One or more modules to exclude from the single line rule.
--tc, --trailing-comma
Includes a trailing comma on multi line imports that include parentheses.
--up, --use-parentheses
Use parentheses for line continuation on length limit instead of slashes.
**NOTE**: This is separate from wrap modes, and only affects how
individual lines that are too long get continued, not sections of multiple
imports.
-l LINE_LENGTH, -w LINE_LENGTH, --line-length LINE_LENGTH, --line-width LINE_LENGTH
The max length of an import line (used for wrapping long imports).
--wl WRAP_LENGTH, --wrap-length WRAP_LENGTH
Specifies how long lines that are wrapped should be, if not set
line_length is used. NOTE: wrap_length must be LOWER than or equal to
line_length.
--case-sensitive Tells isort to include casing when sorting module names
--remove-redundant-aliases
Tells isort to remove redundant aliases from imports, such as `import os
as os`. This defaults to `False` simply because some projects use these
seemingly useless aliases to signify intent and change behaviour.
--honor-noqa Tells isort to honor noqa comments to enforce skipping those comments.
--treat-comment-as-code TREAT_COMMENTS_AS_CODE
Tells isort to treat the specified single line comment(s) as if they are
code.
--treat-all-comment-as-code
Tells isort to treat all single line comments as if they are code.
--formatter FORMATTER
Specifies the name of a formatting plugin to use when producing output.
--color Tells isort to use color in terminal output.

variables.
--split-on-trailing-comma
Split imports list followed by a trailing comma into
VERTICAL_HANGING_INDENT mode
section output options:
--sd DEFAULT_SECTION, --section-default DEFAULT_SECTION
Sets the default section for import options: ('FUTURE', 'STDLIB',
'THIRDPARTY', 'FIRSTPARTY', 'LOCALFOLDER')
--only-sections, --os
Causes imports to be sorted based on their sections like STDLIB,
THIRDPARTY, etc. Within sections, the imports are ordered by their import
style and the imports with the same style maintain their relative
positions.
--ds, --no-sections Put all imports into the same section bucket
--fas, --force-alphabetical-sort
Force all imports to be sorted as a single section
--fss, --force-sort-within-sections
Don't sort straight-style imports (like import sys) before from-style
imports (like from itertools import groupby). Instead, sort the imports by
module, independent of import style.
--hcss, --honor-case-in-force-sorted-sections
Honor `--case-sensitive` when `--force-sort-within-sections` is being
used. Without this option set, `--order-by-type` decides module name
ordering too.
--srss, --sort-relative-in-force-sorted-sections
When using `--force-sort-within-sections`, sort relative imports the same
way as they are sorted when not using that setting.
--fass, --force-alphabetical-sort-within-sections
Force all imports to be sorted alphabetically within a section
-t FORCE_TO_TOP, --top FORCE_TO_TOP
Force specific imports to the top of their appropriate section.

line. Won't work with sections which have 'as' imports
--nlb NO_LINES_BEFORE, --no-lines-before NO_LINES_BEFORE
Sections which should not be split with previous by empty lines
--src SRC_PATHS, --src-path SRC_PATHS
Add an explicitly defined source path (modules within src paths have their
imports automatically categorized as first_party). Glob expansion (`*` and
`**`) is supported for this option.
-b KNOWN_STANDARD_LIBRARY, --builtin KNOWN_STANDARD_LIBRARY
Force isort to recognize a module as part of Python's standard library.
--extra-builtin EXTRA_STANDARD_LIBRARY
Extra modules to be included in the list of ones in Python's standard
library.
-f KNOWN_FUTURE_LIBRARY, --future KNOWN_FUTURE_LIBRARY
Force isort to recognize a module as part of Python's internal future
compatibility libraries. WARNING: this overrides the behavior of
__future__ handling and therefore can result in code that can't execute.
If you're looking to add dependencies such as six, a better option is to
create another section below --future using custom sections. See:
https://github.com/PyCQA/isort#custom-sections-and-ordering and the
discussion here: https://github.com/PyCQA/isort/issues/1463.
-o KNOWN_THIRD_PARTY, --thirdparty KNOWN_THIRD_PARTY
Force isort to recognize a module as being part of a third party library.
-p KNOWN_FIRST_PARTY, --project KNOWN_FIRST_PARTY
Force isort to recognize a module as being part of the current python
project.
--known-local-folder KNOWN_LOCAL_FOLDER
Force isort to recognize a module as being a local folder. Generally, this
is reserved for relative imports (from . import module).
--virtual-env VIRTUAL_ENV
Virtual environment to use for determining whether a package is third-
party
--conda-env CONDA_ENV
Conda environment to use for determining whether a package is third-party
--py {all,2,27,3,310,311,312,313,314,315,36,37,38,39,auto}, --python-version {all,2,27,3,310,311,312,313,314,315,36,37,38,39,auto}
Tells isort to set the known standard library based on the specified
Python version. Default is to assume any Python 3 version could be the
target, and use a union of all stdlib modules across versions. If auto is
specified, the version of the interpreter used to run isort (currently:
310) will be used.
