About this course

Master the core concepts of object-oriented programming by solving practical, real-world coding challenges. Understanding how to structure data and behavior into classes is a fundamental step for any aspiring developer. In this text-based course, you will transition from writing simple scripts to designing clean, reusable Python classes. You will apply these concepts directly by building a geometric area calculator, starting with basic shapes like triangles and expanding to more complex structures. What you'll learn: - Understand foundational object-oriented programming concepts including classes, instances, and methods. - Define custom classes with attributes to store geometric dimensions. - Implement class methods to calculate the area of triangles and other shapes. - Apply modern Python type hints to make your class definitions clear and robust. - Practice writing clean, readable code using standard formatting principles. - Solve structured coding exercises to reinforce your understanding of OOP design. You will begin with essential terminology and the core mechanics of class definition, before moving on to hands-on written exercises that guide you through implementing and testing your calculations. This course is designed for beginners who have a basic grasp of Python variables and functions but are ready to learn object-oriented programming. No prior OOP experience is required. Start reading today to build your confidence in object-oriented Python design.
