Another library you might find interesting is sympy for doing symbolic
calculations:
https://www.sympy.org/en/index.html

If you have sympy installed then you can do things like:

>>> from sympy import *
>>> x = Symbol('x')
>>> equation = 2*x**2 - 1
>>> equation
2*x**2 - 1
>>> equation.diff(x)
4*x
>>> solve(equation, x)
[-sqrt(2)/2, sqrt(2)/2]

Sympy also has a subsection for various topics in physics including
some quantum computing:
