SymPyCore provides a Julian interface to the SymPy library of Python.
SymPyPythonCall utilizes SymPyCore and the PythonCall package (to provide the interop between Julia and Python) to enable access to Python's SymPy library using the practices and idioms of Julia.
The package SymPyPyCall does a similar thing with the PyCall package providing the interop.
Installing this package should install the SymPyCore package and the PythonCall package. The PythonCall package installs a CondaPkg package that installs the underlying SymPy library for Python.
