Clean architecture is a software design methodology that separates the processes of an application into discrete steps instead of presenting them as “spaghetti code.” With the versatility of Python, software engineers can build performant, modular applications quickly using the Flask framework.

This course will help you build better applications using the principles of clean architecture. You’ll start with an introduction to data flow in clean systems and learn about the advantages of layered architectures. Next, you’ll learn system components and the connections between application layers. You’ll then design and build a clean system using Python by layering components in guided coding exercises. Finally, you’ll learn how to add functional components for the web, handle errors, and work with external databases using both Postgres and MongoDB. At each step, you’ll use test-driven development practices to ensure robust functionality.

Clean Architecture in Python

## Overview

This chapter will analyze software design principles that are collectively known as clean architecture. But before we dive into the implementation of these principles, which is the central concern of this course, we need to analyze the structure and components of systems with clean architecture a bit more deeply.

Before we dive into a possible implementation of them, which is the core of this course, we need to analyze more in-depth the structure of the clean architecture and the components we can find in the system designed following it.
