Getting Started#

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python.

SymPy is…

  • 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.
