What is SymPy?

SymPy is a computer algebra system (CAS) written in the Python programming language. SymPy is easy to use and install (see the download instructions and tutorial for more information), and works everywhere where Python 3.8 or newer is installed (Linux, Windows, Mac OS X, ...). SymPy's features include:

  • Arbitrary precision integers, rationals and floats, as well as symbolic expressions
  • Simplification (grouping like a*b*b + 2*b*a*b3*a*b**2, expansion like expand((a + b)**2)a**2 + 2*a*b + b**2, and other methods of rewriting expressions (cancel, factor, collect, etc...)
  • Functions (exp, log, sin, ...)
  • Complex numbers (like exp(I*x).expand(complex=True)cos(x)+I*sin(x))
  • Taylor (Laurent) series and limits
  • Differentiation and integration


The main SymPy documentation is maintained at (where you can see both the development and the latest stable versions docs). The full change log can be viewed here.

The issue tracker is located at

The best place to begin is the Tutorial. A lot of useful information can also be found in the following:
