What are some real-world examples of composition in Python?

Composition in Python is a design principle where a class is composed of one or more objects from other classes. For example, consider a Car class that is composed of Engine and Wheel classes. This allows for more flexible and modular code.

Can you give me another example?

Sure! Think of a Library class that contains Book and Member classes. The Library can manage multiple Books and Members, showcasing how composition allows for complex relationships between objects.

How does composition differ from inheritance?

Great question! Inheritance creates a parent-child relationship, while composition creates a 'has-a' relationship. For instance, a Dog class might inherit from an Animal class, but a Car class has an Engine class through composition.

What are the benefits of using composition?

Composition promotes code reusability and flexibility. It allows you to change the behavior of a class at runtime by composing it with different objects, making your code easier to maintain and extend.
