The Object-Oriented Programming (OOP) paradigm is a programming methodology or approach that is based on the concept of "objects." It's a way of designing and organizing code to model real-world entities and their interactions. The OOP paradigm encompasses a set of principles and concepts that help developers create more modular, reusable, and maintainable software. The OOP paradigm is widely used in various programming languages, including Python, Java, C++, and many others, because it promotes code organization, reusability, and maintainability. It provides a structured approach to software development, making it easier to manage and extend codebases, collaborate with other developers, and model complex systems. In few words, OOP is the way how programmer see the world around.
