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. It depends on mpmath, and other external libraries
|
|
may be optionally for things like plotting support.
|
|
|
|
See the webpage for more information and documentation:
