Python - OOP Concepts

Python Object-Oriented Programming (OOP) Concepts

• Definition: OOP is a programming paradigm based on the concept of "objects," which represent real-world entities containing both state (data) and behavior (functions).
• Core Components:
  • Attributes: Data associated with an object (e.g., a student's name, an employee's salary, or a car's brand).
  • Behavior: Functions that process or manipulate those attributes (e.g., calculating a student's percentage or a car's speed).
• The Class Concept: A class acts as a blueprint that encapsulates attributes and behavior into a single unit, ensuring they co-exist rather than remaining independent.
• Procedural vs. OOP:
  • Procedural Approach: Uses a top-down structure with functions and global data. It is often difficult to maintain, relies heavily on global variables, and treats data as secondary to the process.
  • OOP Approach: Focuses on real-world modeling where data and functions are tightly coupled, leading to better organization and maintainability.
• Key OOP Features in Python: Python provides robust support for OOP, including classes, objects, inheritance, polymorphism, encapsulation, abstraction, and various advanced concepts like metaclasses and decorators.
