Why HN recommends it
Practical guide to applying domain-driven design, test-driven development and event-driven patterns in Python, with worked examples of isolating the domain; suited to working engineers moving past basic Python.
Common criticism: Some find the examples too trivial and a few patterns overly complex.

Architecture Patterns with Python: Enabling Test-Driven Development, Domain-Driven Design, and Event-Driven Microservices by Bob Gregory and Harry Percival
on “Can anyone recommend event-driven architecture book?” ↗I am also very interested to hear opinions on DDD. I recently finished _Architecture Patterns with Python_ [0] which talks about DDD and it was very good. They show some examples of what it looks like to properly highlight and isolate the domain and that was immediately applicable in my work. I am currently…
on “Ask HN: What do you think about Domain Driven Design?” ↗…1. Pycon videos - they're posted free on youtube. It's a great way to explore interesting problems with interesting people. 2. Another book on python by Harry Percival (he does a lot of TDD stuff) - Architecture Patterns with Python. This book is relatively new. It targets an rather niche audience (web devs). But it's hard-won knowledge and really well written. It's a wonderful resource for python devs, and a book I wish more people…

on “Hexagonal Architecture and Domain Driven Design” ↗I'm guessing this was submitted after the "Ask HN" about leveling up to a production python programmer and i'm surprised no one mentioned these books: 1. Test-Driven Development with Python 2. Architecture Patterns with Python The 2nd one is the closest you're gonna get to a production-grade tutorial book.

I've read a lot about DDD but things just don't seem to click for me, partly because example are trivial. For example, I read "Architecture Patterns with Python" (https://www.cosmicpython.com/book/preface.html) but just didn't find it practical. Some random thoughts I had while reading, in no particular order: * what if domain logic can be optimized in the database?…
