isort your imports, so you don't have to.

isort is a Python utility / library to sort imports alphabetically and automatically separate into sections and by type. It provides a command line utility, Python library and plugins for various editors to quickly sort all your imports. It requires Python 3.8+ to run but supports formatting Python 2 code too.

Example Usage

Before isort:

from my_lib import Object

import os

from my_lib import Object3

from my_lib import Object2

import sys

from third_party import lib15, lib1, lib2, lib3, lib4, lib5, lib6, lib7, lib8, lib9, lib10, lib11, lib12, lib13, lib14

import sys

from __future__ import absolute_import

from third_party import lib3


After isort:

from __future__ import absolute_import

import os
import sys

from third_party import (lib1, lib2, lib3, lib4, lib5, lib6, lib7, lib8,
                         lib9, lib10, lib11, lib12, lib13, lib14, lib15)

from my_lib import Object, Object2, Object3


Installing isort

Installing isort is as simple as:

pip install isort

Using isort

From the command line:

To run on specific files:

isort mypythonfile.py mypythonfile2.py

To apply recursively:

isort .

If globstar is enabled, isort . is equivalent to:

isort **/*.py

To view proposed changes without applying them:

isort mypythonfile.py --diff

Finally, to atomically run isort against a project, only applying changes if they don't introduce syntax errors:

isort --atomic .

(Note: this is disabled by default, as it prevents isort from running against code written using a different version of Python.)

From within Python:

import isort



import isort

sorted_code = isort.code("import b\nimport a\n")

Installing isort's for your preferred text editor

Several plugins have been written that enable to use isort from within a variety of text-editors. You can find a full list of them on the isort wiki. Additionally, I will enthusiastically accept pull requests that include plugins for other text editors and add documentation for them as I am notified.

Multi line output modes

You will notice above the "multi_line_output" setting. This setting defines how from imports wrap when they extend past the line_length limit and has 12 possible settings.


To change the how constant indents appear - simply change the indent property with the following accepted formats:

For example:

"    "

is equivalent to 4.

For the import styles that use parentheses, you can control whether or not to include a trailing comma after the last import with the include_trailing_comma option (defaults to False).

Intelligently Balanced Multi-line Imports

As of isort 3.1.0 support for balanced multi-line imports has been added. With this enabled isort will dynamically change the import length to the one that produces the most balanced grid, while staying below the maximum import length defined.


from __future__ import (absolute_import, division,
                        print_function, unicode_literals)

Will be produced instead of:

from __future__ import (absolute_import, division, print_function,

To enable this set balanced_wrapping to True in your config or pass the -e option into the command line utility.

Custom Sections and Ordering

isort provides configuration options to change almost every aspect of how imports are organized, ordered, or grouped together in sections.

Click here for an overview of all these options.

Skip processing of imports (outside of configuration)

To make isort ignore a single import simply add a comment at the end of the import line containing the text isort:skip:

import module  # isort:skip


from xyz import (abc,  # isort:skip

To make isort skip an entire file simply add isort:skip_file to the module's doc string:

""" my_module.py
    Best module ever


import b
import a

Adding or removing an import from multiple files

isort can be ran or configured to add / remove imports automatically.

See a complete guide here.

Using isort to verify code

The --check-only option

isort can also be used to verify that code is correctly formatted by running it with -c. Any files that contain incorrectly sorted and/or formatted imports will be outputted to stderr.

isort **/*.py -c -v

SUCCESS: /home/timothy/Projects/Open_Source/isort/isort_kate_plugin.py Everything Looks Good!
ERROR: /home/timothy/Projects/Open_Source/isort/isort/isort.py Imports are incorrectly sorted.

One great place this can be used is with a pre-commit git hook, such as this one by @acdha:


This can help to ensure a certain level of code quality throughout a project.

Git hook

isort provides a hook function that can be integrated into your Git pre-commit script to check Python code before committing.

More info here.

Setuptools integration

Upon installation, isort enables a setuptools command that checks Python files declared by your project.

Why isort?

isort simply stands for import sort. It was originally called "sortImports" however I got tired of typing the extra characters and came to the realization camelCase is not pythonic.

I wrote isort because in an organization I used to work in the manager came in one day and decided all code must have alphabetically sorted imports. The code base was huge - and he meant for us to do it by hand. However, being a programmer - I'm too lazy to spend 8 hours mindlessly performing a function, but not too lazy to spend 16 hours automating it. I was given permission to open source sortImports and here we are :)

Get professionally supported isort with the Tidelift Subscription

Professional support for isort is available as part of the Tidelift Subscription.
