Pymbolic is a small expression tree and symbolic manipulation library. Two

things set it apart from other libraries of its kind:

* Users can easily write their own symbolic operations, simply by deriving

  from the builtin visitor classes.

* Users can easily add their own symbolic entities to do calculations

  with.

Pymbolic currently understands regular arithmetic expressions, derivatives,

sparse polynomials, fractions, term substitution, expansion. It automatically

performs constant folding, and it can compile its expressions into Python

bytecode for fast(er) execution.

If you are looking for a full-blown Computer Algebra System, look at

`sympy `_ or

`PyGinac `_. If you are looking for a

basic, small and extensible set of symbolic operations, pymbolic may

well be for you.
