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

isort is a Python utility / library to sort imports alphabetically, and automatically separated 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 3.6+ to run but supports formatting Python 2 code too.

Installing isort

Installing isort is as simple as:

Install isort with requirements.txt support:

Install isort with Pipfile support:

Install isort with both formats support:

Using isort

From the command line:

To run on specific files:

To apply recursively:

To view proposed changes without applying them:

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

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

From within Python:

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.

Indentation

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.

Will be produced instead of:

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 :

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

Adding or removing an import from multiple files

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

Using isort to verify code

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.

Setuptools integration

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

For KDE 4.13+ / Pate 2.0+:

For all older versions:

You will then need to restart kate and enable Python Plugins as well as the isort plugin itself.

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.

How does isort work?

isort parses specified files for global level import lines (imports outside of try / except blocks, functions, etc..) and puts them all at the top of the file grouped together by the type of import:

Inside of each section the imports are sorted alphabetically. isort automatically removes duplicate python imports, and wraps long from imports to the specified line length (defaults to 79).

When will isort not work?

If you ever have the situation where you need to have a try / except block in the middle of top-level imports or if your import order is directly linked to precedence.

For example: a common practice in Django settings files is importing * from various settings files to form a new settings file. In this case if any of the imports change order you are changing the settings definition itself.

Configuring isort

If you find the default isort settings do not work well for your project, isort provides several ways to adjust the behavior.

To configure isort for a single user create a

Or, if you prefer, you can add an isort or tool:isort section to your project’s setup.cfg or tox.ini file with any desired settings.

You can also add your desired settings under a [tool.isort] section in your pyproject.toml file.

You can then override any of these settings by using command line arguments, or by passing in override values to the SortImports class.

Finally, as of version 3.0 isort supports editorconfig files using the standard syntax defined here: https://editorconfig.org/

For a full list of isort settings and their meanings take a look at the isort wiki _.

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 6 possible settings:

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 ).

It is also possible to opt-in to sorting imports by length for only specific sections by using length_sort_ followed by the section name as a configuration item, e.g.

Adding an import to multiple files

isort makes it easy to add an import statement across multiple files, while being assured it’s correctly placed.

Git hook

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

If you just want to display warnings, but allow the commit to happen anyway, call git_hook without the strict parameter. If you want to display warnings, but not also fix the code, call git_hook without the modify parameter.

Setuptools integration

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

Issues

Interopability with black

Hey, Timothy! Thanks for isort, it’s a very useful project.

I made an opinionated formatter, Black. Quite a few of my users are also isort users. That’s great, I don’t want to have to perform import sorting in Black. However, there’s a small issue.

None of isort’s multiline modes fits what Black is doing. Black wraps lines like this:

The second step in Black’s algorithm is like your mode 5, and the third is like mode 3. I’d like to create a pull request for isort to introduce mode 8 (5+3) that does what Black does in this scenario. This would enable Black and isort to co-exist and keep consistent import styling.

Would you accept such pull request?

(I initially wrote this on Twitter but this belongs here better.)

enhancement ongoing black

skip statements

Some statements need to be nested within imports, is there a way for isort to ignore them?

Here’s the motivating example:

the use Agg must be called before the plt import. isort:skip doesn’t work here.

isort does not skip files

Describe the bug

isort does not respect skip and skip_glob configuration options.

To Reproduce

Steps to reproduce the behavior:

Expected behavior

A file.py is skipped and is not touched.

Screenshots

Environment (please complete the following information):

Additional context

isort 4.3.10 is working correctly. Issue can be reproduced with skip option as well.

isort behavior different on linux vs osx even with config

Cloud based CI platform (Circle CI / ubuntu)

TLDR, isort requires a different number of newlines on ubuntu.

Add configuration to ensure a newline before each comment

This adds a ensure_newline_before_comments configuration that matches the format that black imposes (for better or worse) and allows isort to be used with black without any thrashing/conflicts with regards to blank lines before comments.

Should help address https://github.com/psf/black/issues/251

Integration with PyCharm

ast and others not considered standard lib

Upgrading from 4.2.5 to 4.2.8, it seems that isort now does not recognize ast as a standard library anymore. We can see it’s doc here in standard library so I think it really should be considered stdlib :/

New release

Is it possible to release a new version please? I want to start using the recent changes for supporting pyproject.yaml.

‘skip’ option does not support ignore directories, similar like flake8 does

I would set isort to ignore all the django migration files. is there any way to do this?

[regression] Inconsistent results on travis-ci

After the last release I started to get inconsistent results on travis again (python3).

I cannot replicate and fix the issues.

I opened this issue even though I don’t have much details to offer, hoping that if more people are experiencing the same problem they will help to debug, for now I will try to pin the test requirements to the previous stable version.

Checks fail with float_to_top and add_imports

Checks always fails when using float_to_top and add_imports together (version 5.10.1).

When running isort on my project, it is always «fixing» all files with no diff, and chacks always fail on all files:

Minimal step to reproduce

There is a regression test here for that particular combination but it doesn’t cover code check. https://github.com/PyCQA/isort/blob/7cf1bf2d0b6c5fcd96693beb80c6222a9ccd0e6a/tests/unit/test_regressions.py#L1403

Long package and module names cause isort to violate the line length limit

I have code with a long import like this:

I run isort on that file like so:

I get imports formatted like this:

Note that the import crosses the 79-character line length limit. This causes errors with my linters, because they correctly complain about the line length limit being violated.

`HANGING_INDENT` Multi Line Import adds comma in profile hug

I have imports like so:

I run isort on that file like so:

I get superfluous commas in the imports:

This is not valid Python syntax and thus even causes errors when trying to execute the file:

Fix NOQA multiline mode. Use «NOQA: E501» instead of excessive «NOQA»…

if we have something like this as input (with a comment other than «# NOQA»):

then we get the following error over and over again:

This problem is relevant if, for example, we want to clarify that we are only interested in ignoring the error by the length of the line.

Also, I changed to use the default «NOQA: E501» instead of the excessive «NOQA» (with the ability for the user to change this to other variations in the comment code)

`lines_before_import` seems to not always work on files

Here is the minimal example is created:

This might or might not be related to https://github.com/PyCQA/isort/issues/1854

Comments in group imports are moved to a single line causing line too long violation (black, flake8)

Hi, this issue seems to be related to #1009 #1843.

When using isort as a pre-commit hook with black profile. My commented imports are being moved to a single line.

My pre-commit hook configuration:

Add some documentation about how isort moves comments.

I spent some time trying to figure out this behavior, or see if there was some way to configure it.

In particular, I was looking to see if there was a way to change some the behavior. A few of things I was looking for a. the ability to have a comment on a multiline import be on the line following the from module import ( line, rather than on it b. the ability to have a comment on the line before an import item in a multiline import sort with that import. c. the ability to have import items with trailing comments kept in the original multiline import, rather than floated to the top.

I realize that a comment before the first import item would have an ambiguous interpretation if both (a) and (b) were supported. These occurred to me at different times looking at specific places where I had comments, and trying to figure out a way to have comments near the appropriate thing in each case. If I had known about (1) and (3), I probably would have spent less time trying to find a way to do (a) or (b) (though (c) would still be useful, I think).

Comments moving bug when using import aliases

I’m seeing a bug(?) where if a from import has an alias, is too long for a single line, and has a comment after the import (for instance a mypy comment) then the comment is getting incorrectly sorted onto the wrong line. See the example below:

Input: test.py

Expected No change; comment stays on line as this is the actual line that mypy complains about.

Observed

Comment is shifted down onto the alias line instead.

Caching in isort

In reference to https://github.com/PyCQA/isort/pull/1738#issuecomment-850901923 of using caching to improve isort performance. As you said, I would refer to the cache implementation in black and model my implementation based on that and like I did with the multiple config enhancement, I’ll open a WIP PR and keep updating and collecting reviews regarding my work. @timothycrosley sounds good?

Add an option to add newline between import groups as per `flake8-import-order`’s hints

Basically my suggestion is to turn this:

(the double newline separates bultins from 3rd party modules)

flake8-import-order also gives a hint to do this on the google preset, while isort ‘s google preset doesn’t separate the groups, so either one of the two utilities is going against the style guideline or it’s undefined by google

EDIT: didn’t notice the code block formatting was wrong, also the code example for output was a bit wrong too
