## What it is
Companion example application code for the book 'Architecture Patterns with Python' by cosmicpython. Each chapter has its own branch demonstrating patterns like service layers, domain modeling, and event-driven architecture with tests and Docker setup.

## Use cases
- learn architecture patterns with python
- example code for domain-driven design in python
- how to structure a python service layer
- study event-driven architecture examples
- code along with the architecture patterns with python book
- see unit, integration and e2e test setup in python

## When to choose
- you are reading the 'Architecture Patterns with Python' book and want to follow along
- you want a worked example of DDD, service layers, and event-driven patterns in Python
- you want to see how to organize unit, integration, and e2e tests with Docker Compose

## When to avoid
- you need a production-ready framework or library to drop into your project
- you want a standalone application rather than educational example code
- you are not working in Python or with Docker

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, testing, e2e-testing
- domain: developer-tools, tutorials, backend, web-development
- platform: python, cross-platform
- tags: architecture-patterns, example-code, book-companion, ddd, clean-architecture, docker-compose, docker
