Introduction
In this fast changing tech world python has become one of the most popular programming languages for both beginners and professionals. It is because of its simple syntax, readability and versatility make it suitable for web development, data science, artificial intelligence and software engineering. Object Oriented Programming is the most powerful feature in Python. a programming paradigm which allows developers to structure code efficiently using classes and objects.
If you are planning to build a scalable and reusable software then learning OOP is very important. At Techpragna Training Institute Bangalore’s leading IT training center teaches students step-by-step through real-world OOP examples and that will help to master concepts like classes, inheritance and encapsulation. This will help the learners not only understand theory but also to apply practically in Python projects.

1. Introduction to Object-Oriented Programming
The method of structuring a program by bundling related properties and behaviors into individual objects is called Object Oriented Programming. In simple terms, OOP allows programmers to model real-world entities in code.
I will give you an example if you are creating a car management system and each car can be represented as an object with attributes like color, model and speed and methods like start(), stop() and accelerate(). This is making the code modular, easy to maintain and reusable.
Python supports multiple programming paradigms but its OOP implementation is especially clean and beginner-friendly.
2. Why Object-Oriented Programming is Important
Below are the key benefits of OOP:
- Modularity – You can divide a large program into smaller manageable parts.
- Reusability – Once you create a class you can reuse it in multiple projects.
- Maintainability – OOP reduces redundancy and improves code readability.
- Scalability – Adding new features or modifying existing ones becomes easy.
- Real-world modeling – OOP makes it simple to represent real-world entities like students, employees or products.
Everything is an object in Python from strings and lists to user-defined data types. That means once you understand the OOP concept then you can understand how python truly works behind the scenes.
3. Understanding Classes in Python
In Python A class is like a blueprint for creating objects. It defines the structure and behavior of objects using attributes (variables) and methods (functions).
Below is the simple example:
class Car:
def __init__(self, brand, color):
self.brand = brand
self.color = color
def start(self):
print(f”{self.brand} car has started.”)
In this example:
- The car is the class.
- brand and color are attributes.
- start() is a method that performs an action.
Classes act as templates helping you create multiple objects with similar properties.
4. Understanding Objects in Python
An object is an instance of a class. It represents a specific entity with unique characteristics defined by the class.
car1 = Car(“Tata”, “Red”)
car2 = Car(“Honda”, “Blue”)
car1.start() # Output: Tata car has started.
car2.start() # Output: Honda car has started.
Here car1 and car2 are two objects created from the Car class. Each object stores its own values for attributes like brand and color.
Objects bring classes to life by turning blueprints into real entities in memory.
5. The Role of the __init__ Method
The __init__ method in Python is a special constructor that automatically runs when a new object is created. It initializes the object’s attributes with specific values.
For example:
class Student:
def __init__(self, name, course):
self.name = name
self.course = course
Here when you create an object:
s1 = Student(“Amit”, “Python”)
The __init__ method assigns:
- self.name = “Amit”
- self.course = “Python”
It is one of the most important parts of the OOP in Python. Because it makes sure that every object starts with properly assigned data.
6. What is self in Python?
The keyword self in Python represents the current instance of the class. It allows access to the object’s attributes and methods.
When you write:
def __init__(self, name):
self.name = name
The self parameter makes sure that the attribute name belongs to that particular object. Without self Python would not know which instance the variable refers to.
Even though you don’t pass self explicitly while creating an object but still Python automatically handles it behind the scenes.
7. Advantages of Using OOP in Python
Below are some major benefits of using OOP in Python include:
- Reusability: You can reuse classes in multiple projects without rewriting code.
- Data Security (Encapsulation): You can restrict access to internal data using private attributes.
- Inheritance: You can create new classes based on existing ones, reducing code duplication.
- Polymorphism: You can define multiple behaviors for a single interface.
- Ease of Maintenance: Updating or fixing code becomes easier as each class handles a specific responsibility.
- Flexibility: OOP makes it easier to adapt to changing project requirements.
Because of these advantages Python’s OOP model has become the foundation for large-scale applications and frameworks such as Django, Flask and TensorFlow.
