Challenge 5: Classes
Classes
Classes form the backbone of Object-Oriented Programming (OOP) in Python. Their integral role is evident in:
- Encapsulation: Classes allow bundling of data and methods that operate on that data within a single unit, ensuring cohesion and modularity.
- Inheritance: It allows creation of a new class that is based on an existing class, promoting code reusability and establishing a relationship between the parent and child class.
- Polymorphism: With classes, one interface can be used for a general class of actions, allowing different classes to be treated as instances of the same class through method overriding.
In summary, classes provide a blueprint for creating objects and a foundation for OOP, facilitating structured and scalable code design.
