Introduction to OOPS

About OOPS

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). A feature of objects is that an object's own procedures can access and often modify the data fields of itself (objects have a notion of this or self). In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types.

Uses of OOPS

• OOP models complex things as reproducible, simple structures
• Reusable, OOP objects can be used across programs
• Allows for class-specific behavior through polymorphism
• Easier to debug, classes often contain all applicable information to them
• Secure, protects information through encapsulation

Why OOPS in Python?

Like other general-purpose programming languages, Python is also an object-oriented language since its beginning. It allows us to develop applications using an Object-Oriented approach. In Python, we can easily create and use classes and objects. An object-oriented paradigm is to design the program using classes and objects. The object is related to real-word entities such as book, house, pencil, etc. The oops concept focuses on writing the reusable code. It is a widespread technique to solve the problem by creating objects.

Principles of object-oriented programming system in Python

• Class
• Object
• Method
• Inheritance
• Polymorphism
• Data Abstraction
• Encapsulation
