isort is a Python utility and library that automatically organises import statements. It helps developers maintain consistent import sections without manually rearranging modules whenever dependencies change.
The program can be used from the command line, called through its Python API, or integrated with development environments. It is particularly useful in projects containing numerous modules and third-party dependencies, where inconsistent import ordering can make source code harder to follow.
isort offers extensive configuration, allowing developers to adopt established formatting conventions or define their own. It can operate independently or alongside general-purpose Python formatters such as Black.
This is free and open source software.
Key Features
- Automatically sorts Python imports alphabetically.
- Separates imports into sections for standard library, third-party, first-party, future and relative modules.
- Supports numerous formatting profiles, including compatibility with Black.
- Offers configurable line lengths, indentation and multiline import formatting.
- Provides several wrapping styles for lengthy import statements.
- Detects and removes duplicate imports.
- Can process individual files or recursively organise imports throughout a project.
- Provides check and diff modes to validate imports without modifying files.
- Offers an atomic mode that checks syntax before applying changes.
- Supports configuration through pyproject.toml and other project configuration files.
- Allows selected imports and files to be excluded from processing.
- Can add or remove specified imports through command-line options.
- Provides a Python API for sorting source code programmatically.
- Integrates with code editors, pre-commit hooks and automated development workflows.
