Inheritance 🧩

Inheritance allows a class to inherit properties and methods from another class. This promotes code reuse and hierarchical relationships.

Example

class Animal:
    def speak(self):
        pass

class Dog(Animal):
    def speak(self):
        return "Woof!"

Polymorphism 🎭

Polymorphism enables objects of different classes to be treated as objects of a common superclass. It allows methods to do different things based on the object it is acting upon.

Use Cases

  • Method overriding
  • Interface implementation
  • Abstract classes

Abstraction 📦

Abstraction hides complex implementation details and shows only essential features of an object. It simplifies interactions with complex systems.

Interfaces 🔌

Interfaces define a contract for classes to follow. They specify methods that must be implemented but do not provide the implementation details.
