Software Design in Python - Refactoring A Data Science Project Part 1 - Abstraction and Composition

💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide. This is the first part of a 3-part miniseries in which I refactor a hand-written digit recognition data science project based on the MNIST dataset to improve the software design so it's easier to reuse and adapt. In this first part I cover using abstract classes and protocols to better separate the various aspects of the application, and I talk about function composition as a generic solution to dealing with data pipelines.
