Python OOP Tutorial 5: Special (Magic/Dunder) Methods
In this Python Object-Oriented Tutorial, we will be learning about special methods. These are also called magic or dunder methods. These methods allow us to emulate built-in types or implement operator overloading. These can be extremely powerful if used correctly. We will start by writing a few special methods of our own and then look at how some of them are used in the Standard Library. Let's get started.

@@coreyms your a rock star!!! Good stuff.
best python tutorials on youtube. period.
I started with Python from two weeks ago I come from Php and Java so I have a good understanding of Classes and Objects, but I have to tell you that the way you present every topic is magistral. Thank you very much for your flawless tutorial. And the extra for me is that your tutorials are also an English class.
These OOP tutorials are worth gold! They make difficult subject to look so easy!
@Corey - You are an excellent teacher and know exactly how to tell/teach about any topic. I have seen all of your videos and learnt a lot by watching these tutorials. Can you please upload some videos on some of the python concepts like - Multiprocessing, Design patterns, MetaClasses as well.
My favorite part of your tutorials is that you give a great great example come from standard or well-known library to show us what those skills are used in dealing with real-world programming issues. A hundred thumb-ups!
Keep up the Python OOP tutorial, they're great!
So clear, concise, and precise. Best Python tutorials I have yet come across on KZread
I had an ungodly amount of trouble understanding OOP in general and I think that in the middle of many other tutorials, yours were the first that I could finally understand and keep up with without getting lost halfway through the lecture. Thank you so much, keep the wonderful content coming! ♥
Great series of tutorials on OOP! I really love them. Very clear and with a speedy pace!
You are like the Khan Academy of Python code. Great explanations and examples.
These videos are such a lifesaver for me. Gives me actual understanding instead of me just stumbling along, not knowing what I'm really doing.
This video specifically has opened some doors for me in understanding classes and special methods used inside algorithms. Always learning something new each day on my coding journey!!! It never stops and I love it!!
You Sir need a million subs just for teaching this one episode. So clean and precise!! Thank you for the work you put in we really appreciate it.
DUDE you're the fkn MAN.. been following this series and everything about your presentation is SO great. Thank you so much :) I will be donating
Who is down voting your videos? You are a master and clearly demonstrate your command of this language by how easily you simplify these concepts for me. Thank you, good sir!
you kick ass! This has been invaluable to a university project I'm working on at the moment Thanks!
I have just spent the day going through this series as I am studying and needed to understand this concept better. Your series has been superb and I'm so thankful. Thank you for sharing your extensive knowledge in a way that is clear and easy to understand. When I am working I will support through Patreon to pay it forward so you keep on making them. I am going to watch many more of your videos from here on, I am sure.

Probably the best tutorial of OOPS in the world. 👌
This was a great video. I've been curious about operator overrides in python for a little bit. Blundered into the answers in this video and within 30 minutes had a working Vector class from scratch that handles all the basics. Thanks much for the really excellent content on your channel. I have to echo the other folks who point out how well you present the information. Well done!
My eyes have finally opened to so many things in python! Thanks!
Ive been watching your videos and they have already helped me in my Job as a Site Reliability Engineer to write better python code, you have also helped me understand concepts that I haven't truly understood for the years Ive been in software development. Thank you for your great explanations. You definitely are making a great difference in peoples lives. Keep on Keeping on!
Finally, I understand Classes. Thank you!
Your tutorials take into depth, which is something others of same kind never did. I'm lucky finding you.
Exactly what I needed. Clear, comprehensive and great examples! Nice work man!
been playing around with code trying to learn and I've just watched the four previous videos on classes, they're the one thing I've had issues with during my year of coding so far, and your videos helped me figure out how to incorporate them into my lil pygame, so thanks! good job breaking them down and explaining each part of them! I'll finish this one tomorrow morning 😁
Corey, thanks for your tutorials, you are clear to the point, and avoid waffle. The dunder methods are helping me debug my app much more efficiently.
I finally feel I have a complete picture on Python basics despite already learning it for 4 months. Thanks.

If I ever had a any doubts on python I would look no further than your playlist. I recommend people to refer your videos first because it's no time-wasting around and just pure content.. Plus hat's off to your clear and concise language with in depth knowledge and a perfect pace while explaining.. Keep up the great work.. You are flamboyant God bless you Corey.. :)
You don't know how much we appreciate your work here Corey, best way of teaching and a good soul, we love you.
Boy am I glad I found this tutorial. II was over my head on OOP. Can't believe how much I've learned in just 5 videos. Right on Corey!!

Exceptionally well, such organized Tutorials are intellectual assets that are really devoted free to learner community.
I am an avid follower of your tutorials from the day KZread recommend me your ___name___ video. I loved it and got hooked to your style of teaching. Today when I got stuck at a problem in Hackerrank, I *Coreyed* the problem (fancy term for Googled when it comes to Python) and voila there it is; the video I wanted! Viel Danke Corey!
Wow changing what it displays is priceless. Thank you for the Dunder explanation!
Thank you for this awesome set of tutorials. I came in from the PHP world and your explanations gave me a headsup to Python OOP
Great tutorial, straight to the point. Thanks Corey!
One of the best python program langauge channel on youtube, Thanks brother from India.
Absolutely recommended video. Crisp and Clear
You have very deep understanding of python, teaching and choosing examples. Its really hard to understand where general student fail and get frustrated and you know this all. Thanks a lot Sir
I love your videos man, seriously I don't get it why in college they don't explain it like you do- I just understood a lot about Python thanks to you. I'm dead serious I was frustrated I didn't got it right, thank you very much for sharing your knowledge !

Really amazing content Corey - really useful detail presented a brisk pace. Thanks so much!
When I was self studying C# because my job needed it, I hardly grasped the concept of OOP because coding it in C# to see how it actually works is complicated. With your explanation, I saw the clear and complete picture of OOP. Maraming Salamat ! (Thank you so much ! 🙂)
Each and every one of your videos is amazing. Thanks for the great content!
Thanks a bunch! Your videos are to the point, concise and yet, very well explained.
Thank you for your videos, Corey! It really helped me better understand how to work with classes in Python :)
You just opened a whole new page of programming to me. Before this I didn’t fully understand oop. Thank you 👍
I just want to say, your videos are excellent. You provide a clear explaination of everything. Thank you. I was having issues with __repr__ and __str__ until I realized that I was putting them in the wrong class. Hopefully this will help anyone else having similar issues.
All your videos are very useful. Keep it up.
Thnx for the video Corey, now i can understand the special methods a little bit
Really Awesome, Amazing flow of wording and content presentation. Thank you very much Schafer.
We have to create another class to remove from KZread those who watched this video but didn't thank Corey. Thank you a lot Corey ! I'm a beginner not only in python, but in all programming languages , but I understood your teaching very well.
Dude, you're awesome. Been binging your videos and they are helping a bunch. Excellent teaching ability!
You deliver the best explanations and clear presentations.
Simply amazing!! The way you are representing anyone who can learn easily, I came from different language background and i can easily compare it the way you explained. Thanks for your videos. Keep it up.
You are great man!! You have helped me a lot in understanding many Python Concepts.
@corey - Your way of explaining the concepts are too good. Keep continue your work.Love your teaching skills. Kudos to you.
I watch this on June 29, 2020, and now I understand why you need __add/len/str/repr__ in a class. Best 30 minutes of time spent on learn and taking note.
Awesome tutorial.. superbly described oops concept... thanku very much..
another great tutorial. really helping to tie together learning from text tutorials and excercises.
Excellent explanation Corey. Thanks for sharing this!
You make learning Python really enjoyable Corey 🙌🏽
great tutorial! I built my first app learning from your videos. Thank you!
this is just awesome! helps me a lot. thank you for your hard work!
It really helped me :) ... I thought I can't understand this topic but you made It clear
