sets out to explain the deeper logic in the approach that Python 3 takes to classes and objects. The subject is roughly speaking everything to do with the way Python implements objects. That is, in order of sophistication, metaclass; class; object; attribute; and all of the other facilities such as functions, methods and the many “magic methods” that Python uses to make it all work. This expanded second edition uses Visual Studio Code and has an Appendix on how to use it with Python.
