In the previous course in the Python Basics series, you learned how to use classes to create new objects. Now that you understand the basics of object-oriented programming (OOP), it’s time to put those classes to work.

In this video course, you’ll learn how to:

  • Compose classes together to create layers of functionality
  • Inherit and override behavior from other classes to create variations
  • Creatively mix and match these approaches

With these capabilities, you’ll be able to build more complex systems and write readable, reusable code.

This video course is part of the Python Basics series, which accompanies Python Basics: A Practical Introduction to Python 3.

Note that you’ll be using IDLE to interact with Python throughout this course. If you’re just getting started, then you might want to check out Python Basics: Setting Up Python before diving into this course.

00:00 Welcome to Python Basics: Building Systems With Classes. To get the most out of this course, ideally you’ll already have some notion of what object-oriented programming in Python looks like.

00:12 You’ll be taking a closer look at the question of how do you actually use classes when coding? And in this course, you’re going to see that you can compose classes together, inherit and override behavior from other classes, and you can mix and match these approaches. This isn’t an exhaustive course.

00:32 This is just an introduction to building systems with classes so you can have an idea about how classes can be worked together into more complex systems.

00:44 This course is part of a series, Python Basics. All the courses in this series use IDLE, the Integrated Development and Learning Environment that comes bundled with Python. If you’re not sure what IDLE is, check out a previous course in the Python Basics series called Setting Up Python, or check out Starting with Python IDLE on realpython.com.

01:08 So with that, let’s get stuck into building systems with classes.
