# Oop

Intro to object-oriented programming concepts in Python.

OOP models real‑world things as objects with data (attributes) and behavior (methods).

## Core Ideas

* **Class**: blueprint for objects
* **Object**: instance of a class
* **Encapsulation**: keep data and behavior together
* **Inheritance**: reuse behavior from a base class
* **Polymorphism**: same interface, different implementations
* **Abstraction**: hide complex details behind a simple interface

## Quick Example

```python
class Dog:
    def __init__(self, name):
        self.name = name

    def speak(self):
        return f"{self.name} says woof"

pet = Dog("Rex")
print(pet.speak())
```
