python:architecture

What problem does it solve?

Python architecture guidance focuses on cleanly separating pure business logic from IO using the functional core / imperative shell pattern, combined with Domain-Driven Design and typed data modeling to improve testability and maintainability.

Core Features & Use Cases

• Functional core / imperative shell: isolates business logic from side effects, enabling deterministic testing.
• Domain-Driven Design (DDD): defines bounded contexts and explicit domain models with transformations.
• Layered architecture guidance: outlines Entities, Repositories, Services, and Adapters to connect to external systems.
• Use Case: architect a new service with clear domain boundaries, a persistence strategy, and integration points for external systems.
