Overview of this book

In the rapidly evolving tech industry, software applications struggle to keep pace with changing business needs, leaving developers grappling with complex codebases that resist change, ultimately reducing productivity and increasing technical debt. Clean Architecture with Python offers a powerful approach to address these challenges. Drawing from his extensive experience architecting cloud-native systems, Sam Keen helps you transform complex architectural challenges into digestible, implementable solutions. This book teaches essential principles for effective development, emphasizing the Pythonic implementation of Clean Architecture. Through practical examples, you'll learn how to create modular, loosely coupled systems that are easy to understand, modify, and extend. The book covers key concepts such as the Dependency Rule, separation of concerns, and domain modeling, all tailored for Python development. By the end of this book, you'll be able to apply Clean Architecture principles effectively in your Python projects. Whether you're building new systems or managing existing ones, you'll have the skills to create more maintainable and adaptable applications. This approach will enhance your ability to respond to changing requirements, setting you up for long-term success in your development career.

Ensuring domain independence

The independence of the Domain layer is a cornerstone of Clean Architecture, directly tied to the Dependency Rule we first introduced in Chapter 1. This rule, stating that dependencies should only point inward toward the Domain layer, is crucial for maintaining the purity and flexibility of our core business logic. In this section, we’ll explore practical applications of this rule and strategies to ensure domain independence.

The Dependency Rule in practice

Let’s examine how the Dependency Rule applies to our task management system, using examples that highlight common violations and their corrections.

Example 1

Task entity with database dependency:

@dataclass
class TaskWithDatabase:
    title: str
    description: str
    db: DbConnection  # This violates the Dependency Rule
    due_date: Optional[Deadline] = None
