Design patterns
Nota bene : This content was generated by AI. I am working on this page to provide personal content of better quality.
Design patterns are proven solutions to recurring software design problems. They are not copy-paste code: they describe structures and collaborations between classes that you adapt to your context.
Three families
| Family | Role |
|---|---|
| Creational | Flexible object creation |
| Structural | Class and object composition |
| Behavioral | Responsibilities and communication |
Examples use Python 3. When helpful, the expected console output is shown below the code.
Covered patterns
- Creational: Abstract Factory, Builder, Factory Method, Prototype, Singleton
- Structural: Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy
- Behavioral: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method, Visitor
