Why SymPy

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.
