Doing Symbolic Math with SymPy

On November 29, version 1.7 of SymPy, a Python library for symbolic mathematics, was released. The new version brings a large number of enhancements and bug fixes, and some minor backward incompatibilities. While these are enumerated in detail in the release notes, we will take advantage of this opportunity to look at some of the things that can be done with SymPy and explore its interface options through several detailed examples.
