This is a complete and practical guide with full project code about Layered Architecture. Even if the code in this is written in Python, these ideas are general programming concepts and design patterns that can be implemented in almost the same way in any OO Language like C++, Java, etc. This is a Zero-To-Hero guide where we will learn everything about the Layered Architecture including advanced stuff and other Design Patterns. Enjoy reading!

In this guide I will show you how to use this architecture and other design patterns (like validator, repository, decorator, etc) to create python applications that can be tested with ease, be scalable, and it will save you a lot (and I mean a lot) of development time in the long run. And the best part is that this is a general-purpose architecture that can be implemented in any language, and can be a backbone architecture for every project you start or work on. I will keep it short with the theory part and I will try to explain more with code.
