- Free: Licensed under BSD, SymPy is free both as in speech and as in beer.
- Python-based: SymPy is written entirely in Python and uses Python for its language.
- Lightweight: SymPy only depends on mpmath, a pure Python library for arbitrary floating point arithmetic, making it easy to use.
- A library: Beyond use as an interactive tool, SymPy can be embedded in other applications and extended with custom functions.
Projects using SymPy
This is an (incomplete) list of projects that use SymPy. If you use SymPy in your project, please let us know on our mailinglist, so that we can add your project here as well.
