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

Data types play an important part in a system. They’re used to encapsulate and transmit information. In particular, when we discuss software systems, it’s important to make sure that types shared by different systems are known to all of those systems. The knowledge of data types and formats is, in fact, a form of coupling. 

Think about the many languages of the world. If we have to talk to an audience, we have to use a language that they understand. This couples us with our audience. This course is in English, which means we’re coupled with English-speaking readers. If all English speakers in the world suddenly decide that they don't want to use English anymore and replace it with Italian, we then need to redesign this course from scratch (though, admittedly, with less effort).

Let’s learn about data types in this lesson.
