This module is a computer algebra system (CAS) written in the Python programming language.
A large can be found on this blog aggregator at planet.sympy.org.
First, You need to install it using pip3.4.

For a short introduction into SymPy python module I will show you the printing features.The most common printers available in SymPy are:
- str
- repr
- ASCII pretty printer
- Unicode pretty printer
- LaTeX
- MathML
- Dot

How to print one matrix :>>> x, y, z = symbols('x, y, z')
>>> init_session(quiet=True)

>>> mat = Matrix([x*y, 1,0,3,-2, sin(z)])
>>> mat

Next example come with this issue: equations can be solved with SymPy python module.>>> solve(x*x+x+2)
___ ___
1 \/ 7 *I 1 \/ 7 *I
[- - - -------, - - + -------]
2 2 2 2
>>> solve(Eq(x*x+x+2))
___ ___
1 \/ 7 *I 1 \/ 7 *I
[- - - -------, - - + -------]
2 2 2 2
>>> solve(Eq(x*x+2*x+4))
___ ___
[-1 - \/ 3 *I, -1 + \/ 3 *I]
>>> solve(x*x+2*x+4)
___ ___
[-1 - \/ 3 *I, -1 + \/ 3 *I]
