Intro to Object-Oriented Programming (OOP) in Python

Object-oriented programming is one of the biggest and most important subjects in all of programming. This series will provide you with a basic conceptual understanding of Object-Oriented Programming so you can take your Python programming skills to the next level.

You’ll learn how to define custom types using classes, and how to instantiate those classes into python objects that can be used throughout your program.

Finally, you’ll learn how classes can subclass one another with brief introduction to inheritance, which allows you to write maintainable and less redundant Python code.

Great tutorial, I watched it several times and kept coming back for clarity. Within days I wrote two classes/modules and had them running. The concepts, especially the architecture framework, are well explained. This helped me finally get into OOP, Thanks

Hi all! I’m new here and for sure me a member was the best thing that I did to keep myself on Python Learn track! All videos, articles and stuffs on this website are amazing! Topics are well explained, lean samples and directly to the point. Nice tutorial!

This was a fantastic intro to OOP! The step-by-step process and clear instruction helped me understand concepts I couldn’t before. One topic that was especially difficult for me was the use of the ‘self’ parameter and the ‘initializer.’ This video tutorial clarified those features of OOP and made it easy for me to use them. I’m excited to build on this knowledge with the other OOP video tutorials at RealPython!! Thanks, Austin!

Excellent!! Crisp and simplistic way of explaining the most confusing terminologies

I have been trying to understand OOP for a while and this is the first tutorial in which I’ve started feeling I know what is all about! Thanks!

Jean Ferreira on Sept. 5, 2019

Very good videos. I started learning the concepts of OOP programming at university, but I needed a more visual way to understand the concepts. Thanks!

Very good intro to OOP in python.

Jordan Rowland on March 23, 2019

Great videos. I found my understanding of OOP was really solidified when working with SQLAlchemy for a Flask project, and having Post and User classes.

Thanks. Well paced and a nicely gentle introduction to OOP. At least it is gentle if you already have the basic concepts and are treating this as a refresher :-)

Peter T on March 22, 2019

Austin did an excellent job of clearly explaining the various OOP topics in all 7 videos, without leaving any gaps or questions. Now, I’m anxiously waiting for the next set of OOP videos to continue to this course & I hope they show up soon. IMHO, there aren’t enough OOP topics in or, but there are tons of other Python-related topics in both sites!
