Скачать или смотреть Python Code Cleanup: From Spaghetti to Structure

Are you tired of wrestling with spaghetti code as your projects grow? In this video, we’ll show you how to transform a messy, unscalable notification system into a clean, modular design using SOLID principles.

We’ll start with a common scenario: a simple Notification class that quickly spirals into chaos as new requirements pile up—like adding WhatsApp notifications, in-app alerts, or custom logic for each type. This relatable example highlights the challenges of poor design and why adhering to solid design principles is crucial for scalable software development.

Then, we’ll walk you through how to refactor the code step by step:
Single Responsibility Principle (SRP): Break down responsibilities into focused classes like EmailSender and SMSSender.
Open/Closed Principle (OCP): Make your system easy to extend without modifying existing code.
Dependency Inversion Principle (DIP): Depend on abstractions, not concrete implementations.

By the end, you’ll see how to create a modular, extensible, and maintainable notification system that’s built to handle future changes with ease.

Perfect for developers aiming to improve their software architecture skills, this video dives into practical coding techniques to simplify your life and create code that’s elegant and reliable.
