Who am I?

• ​​Open Source Python Library
• For Symbolic Computation
• Written entirely in Python
• No dependency except mpmath

What is SymPy?

Study and development of algorithms and software

for manipulating mathematical expressions and other

mathematical objects.

Symbolic Computation

Symbolic vs Numeric?

• Symbolic:  π

• Numeric:  3.14159265359

● Standalone

● Full featured

● BSD licensed

● Embraces Python

● Usable as a library

Why SymPy? 

Provide a symbolic manipulation library in Python.

- en route to a full featured computer algebra system

Goal

● Ondřej Čertík started the project in 2006.

● Lot of work was done in Google Summer of Code 2007.

● Participated in every GSoC for last 9 years.

● Aaron Meurer took over as a lead developer on Jan 4, 2011.
