Ce que vous apprendrez

Spot code smells and measure the cost of change: coupling and cohesion
Apply the SOLID principles and prefer composition over inheritance
Use Factory, Builder and Singleton (and know why to be wary of Singleton)
Use Adapter, Decorator, Facade and Composite to structure code
Use Strategy, Observer, Command, Iterator and Template Method to organise behaviour
Decide when a pattern is worth it and when a plain function is enough, in Python and in Java

No prior knowledge of design patterns

Description

Learn to design code that survives change requests. Each topic starts with a shared concept video: a real change request that hurts, the painful "before" code, the pattern as a class diagram and a step-by-step refactoring, and when the pattern is NOT worth it. Then continue in Python or Java: the same refactoring in real code, the idiomatic version of your language (often just a function in Python), where the standard library already uses it, and the traps. Capstone: refactor the checkout of a small online shop.

À qui s'adresse ce cours

Developers whose code gets harder to change with every feature
Students preparing for interviews or software-design exams
Self-taught programmers who want to write professional, maintainable code
