商品描述
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.

- Make descriptors and discover why you should

商品描述(中文翻譯)
這本關於 Python 描述符的短書是來自多個來源的知識和想法的集合，專注於處理和創建描述符。在介紹所有描述符的共同特徵後，作者探討了多種實現方式的想法，以及一些前所未見的全新概念。
這確實是一本全面的 Python 描述符創建指南。作為額外的收穫：一個可通過 pip 安裝的庫 descriptor_tools 與本書一起編寫，並且是一個開源庫，托管在 GitHub 上。
目前市場上關於編寫 Python 描述符的優質資源不多，書籍更是寥寥可數。這是一個令人遺憾的現狀，因為這使得 Python 開發者難以真正理解描述符的運作方式以及避免與之相關的重大陷阱的技術。
