I think “Architecture Patterns with Python” is a great book on multiple levels. First off it shows the natural progression of you code base as you build out features, achieve higher performance or want to increase reliability. Secondly it nicely puts the theory in to practice. Which perfectly lives up to “Although practicality beats purity” in the Zen of Python.

A second book I think nicely compliments this book is “Clean Code in Python” by Mariano Anaya (https://www.packtpub.com/product/clean-code-in-python/978178...). To really perfect the implementation of the architecture in the first book.

Making beautiful code starts by making every line count. Then by making all lines add up.
