There aren't a ton of really good resources out there for writing Python descriptors, and extremely few books (this may be the only one).
                                                
This book hopes to rectify that situation. Between these covers is a collection of knowledge and ideas from many sources on dealing with and creating descriptors. And, after going through the things all descriptors have in common, it explores ideas that have multiple ways of being implemented as well as completely new ideas never seen elsewhere before.

This truly is a comprehensive guide to creating Python descriptors.

BONUS: A pip installable library, descriptor_tools, was written alongside this book and is an open source library on GitHub at https://github.com/sad2project/descriptor-tools
