Sass for Python: A straightforward binding of libsass for Python.

Project description

PyPI Build Status status

This package provides a simple Python extension module sass which is binding LibSass (written in C/C++ by Hampton Catlin and Aaron Leung). It’s very straightforward and there isn’t any headache related to Python distribution/deployment. That means you can add just libsass into your’s install_requires list or requirements.txt file. No need for Ruby nor Node.js.

It currently supports CPython 3.7+, and PyPy 3!


  • You don’t need any Ruby/Node.js stack at all, for development or deployment either.

  • Fast. (LibSass is written in C++.)

  • Simple API. See the below example code for details.

  • Custom functions.

  • @import callbacks.

  • Support both tabbed (Sass) and braces (SCSS) syntax.

  • WSGI middleware for ease of development. It automatically compiles Sass/SCSS files for each request.

  • setuptools/distutils integration. You can build all Sass/SCSS files using build_sass command.

  • Works also on PyPy.

  • Provides prebuilt wheel binaries for Linux, Windows, and Mac.


It’s available on PyPI, so you can install it using pip (or easy_install):

$ pip install libsass


>>> import sass
>>> print sass.compile(string='a { b { color: blue; } }')
a b {
  color: blue; }


There’s the user guide manual and the full API reference for libsass:

You can build the docs by yourself:

$ cd docs/
$ make html

The built docs will go to docs/_build/html/ directory.


Hong Minhee wrote this Python binding of LibSass.

Hampton Catlin and Aaron Leung wrote LibSass, which is portable C/C++ implementation of Sass.

Hampton Catlin originally designed Sass language and wrote the first reference implementation of it in Ruby.

The above three are all distributed under MIT license.
