ePOM - Intro to Ocean Data Science - Object-Oriented Programming
This document provides an introduction to object-oriented programming and describes how to create a Python module with a class. It defines object-oriented programming as an approach to organize code where an object contains both data and behavior. Classes help create reusable code through concepts like encapsulation, inheritance, and polymorphism. The document then outlines the six steps to create an example class, including minimal definition, initializing attributes, adding initialization parameters, error checking, string representation, and methods. It encourages the reader to create their own Python module and class.

- 5. WHY OBJECT-ORIENTED PROGRAMMING? •Powerful approach to organize your code • An object contains both: • Data → Class variables • Behavior → Methods (Class functions) • Helps on creating reusable code → Don’t Repeat Yourself (DRY) • An object keeps internal a lot of details → Encapsulation • Many other good reasons • AbstracƟon → Helps building complex systems by spliƫng their complexity • Inheritance → A class may inherit data/behavior from other classes + extend them • Polymorphism → The same method may behave differently on different classes • …
