SymPy 0.6.0 has been released on July 7, 2008. It is available at


About SymPy

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 and does not require any external libraries.

user-visible changes:
  • all documentation wiki pages moved to docs.sympy.org
  • mpmath was integrated in SymPy, numerics module removed
  • mpmath can use gmpy optionally, thus calculating 1000000 digits of pi in 7.5s
  • Common subexpression elimination implemented (commit 1, 2, 3, 4), see docs
  • roots, RootsOf, RootSum implemented (commit)
  • lambdify() now accepts Matrices (commit)
  • Matrices polished and spedup (commit 1, 2, 3, 4, 5, 6, 7, 8, 9)
  • source command implemented (commit 1, 2)
  • Polys were made the default polynomials in SymPy (commit 1, + many following commits)
  • Add, Mul, Pow now accept evaluate=False argument (commit)

Plus a lot of smaller bugfixes, you can browse our Mercurial history for details.
