Python Descriptors

by Jacob Zimmerman

This short book on Python descriptors 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, the author 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. As a bonus: A pip install-able library, descriptor_tools, was written alongside this book and is an open source library on GitHub.
There aren't many good resources out there for writing Python descriptors, and extremely few books. This is a sad state of affairs, as it makes it difficult for Python developers to get a really good understanding of how descriptors work and the techniques to avoid the big gotchas associated with working with them.

I enjoyed reading this book, especially the first part, it shows a view point of a developer who is not involved in the core development of python itself. He sometimes also says, ask a core developer if you wanna get the exact reasoning behind it 😄

You don’t need an editor open beside you while reading, so I pretty much read it on the bus.
