Python Test

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

# Rent-o-Matic

The goal of our Rent-o-Matic project is to create a simple search engine for a company that rents rooms. Objects in the dataset (rooms) are described by several attributes. Our search engine will allow the user to set filters to narrow their search according to these attributes.




Let's learn more about the application that we’ll work on in this course.
