Lecture 8 : OOPS in Python | Object Oriented Programming | Classes & Objects | Python Full Course

The chapter introduces Object-Oriented Programming (OOP) in Python, emphasizing its importance in programming and interviews. It covers the fundamental concepts of objects and classes, explaining how OOP relates to real-world scenarios and improves programming practices.

The discussion continues on the significance of OOP, highlighting its relevance in building systems in companies. The chapter aims to clarify the meaning of OOP and its components, such as classes and objects, which are essential for effective programming.

The chapter explains the transition from procedural programming to functional programming and then to OOP, emphasizing the benefits of reusability and reducing redundancy through the use of functions, classes, and objects.

The concept of classes is introduced as blueprints for creating objects. The chapter illustrates how to visualize real-world entities as objects in programming, using examples like students in a classroom.

The chapter elaborates on the relationship between classes and objects, explaining that objects are instances of classes. It discusses how to create classes and instantiate objects, providing examples to clarify these concepts.

The chapter introduces the constructor method, explaining its role in initializing objects. It discusses the self parameter, which refers to the current instance of the class, and how it is used to access attributes and methods within the class.

The chapter explains attributes in OOP, distinguishing between instance attributes (specific to each object) and class attributes (shared among all instances). It provides examples to illustrate how to define and access these attributes.

The chapter discusses methods in classes, explaining how they are functions defined within a class. It emphasizes the importance of the self parameter in methods and provides examples of how to create and call methods in Python.

The chapter introduces the concepts of encapsulation and abstraction in OOP. It explains how encapsulation involves bundling data and methods into a single unit (class) and how abstraction hides unnecessary details from the user.

The chapter presents a practical example of creating a Student class, demonstrating how to implement methods for calculating averages and managing student data. It emphasizes the organization and structure that OOP provides in programming.
