For all the Python devs reading this, a book that aims to cover DDD from a Python perspective is Architecture Patterns With Python [1]. It's free to read online and all the code can be found in Github.

Funny coincidence: just one week ago I and a colleague of mine started with "pytest-arch" [1], a pytest plugin to test for architectural constraints. On purpose we kept it very simple. It is already usable and works well, at least for our use cases.

You can use it to check e.g. if your domain model is importing stuff that it should not import.

We are planning to publish it soon on pypi.
