Add to BookmarkIntroduction to OOP in Python
Object-Oriented Programming (OOP) is a programming paradigm that organizes code using objects and classes. It helps in structuring code in a modular and reusable way.
Key Concepts of OOP:
- Class – A blueprint for creating objects.
- Object – An instance of a class.
- Attributes – Variables that store data for an object.
- Methods – Functions defined inside a class that operate on object attributes.
- Encapsulation – Restricting access to certain details of an object.
- Inheritance – Allowing a class to inherit features from another class.
- Polymorphism – Allowing objects to be treated as instances of their parent class.
Why Use OOP?
- Modularity: Code is structured into reusable components.
- Reusability: Code can be extended without modifying existing functionality.
- Scalability: Helps in managing large codebases.
- Data Protection: Encapsulation restricts direct access to data.
Defining a Simple Class and Object in Python
class Car:
def __init__(self, brand, model):
self.brand = brand # Attribute
self.model = model # Attribute
def display_info(self):
return f"Car: {self.brand} {self.model}"
# Creating an object
my_car = Car("Toyota", "Corolla")
print(my_car.display_info()) # Output: Car: Toyota Corolla
