Object-Oriented Python: Building a Square Sum Calculator

Object-oriented programming is the cornerstone of modern software development, yet transitioning from basic scripts to structured classes can feel daunting. This text-based course guides you step-by-step through the process of defining classes, working with constructors, and implementing practical methods to solve algorithmic problems. You will learn to write clean, reusable code by building a class that squares numbers and returns their sum, reinforcing core programming principles through clear explanations and structured exercises. By the end of this course, you will confidently structure Python classes, manage object states with constructors, and implement custom methods to perform calculations on object properties. What you'll learn: - Understand foundational object-oriented programming concepts and terminology - Construct Python classes with custom initializers and public properties - Implement instance methods to perform mathematical operations on object data - Apply type hints to class attributes and method signatures for modern, readable code - Practice writing clean, maintainable object-oriented code through targeted exercises We begin with the absolute basics of object-oriented design, defining what classes and objects are before moving into constructors and property assignment. From there, you will write custom methods to process data inside your objects, culminating in a hands-on mathematical challenge. This course is designed for beginner Python programmers who understand basic syntax and want to transition into object-oriented design. No prior experience with classes or OOP is required.
