Inheritance/Polymorphism in Object Oriented Programming | Python for Beginners | Code with Kylie #10
We are LEVELING UP our object oriented programming. Once you start creating objects in Python using classes, you can step up your OOP game by incorporating inheritance and polymorphism!
Inheritance is when you can create child classes that inherit attributes and functions from the parent. These are often used when you have a more general overarching class but want to define more specific classes that may be similar but not quite the same. We do this in order to avoid copy-and-pasting a gazillion times.
In this video, we use dogs as an example of how inheritance can be used. I demonstrate how to create a parent class (superclass) and child class (subclass), and initialize both of them.
We can also have multiple inheritance, which is when a subclass can have multiple parents and inherits the unique functions and attributes of both of them. An example is a golden doodle!
Polymorphism is related to inheritance. Polymorphism means taking many forms. In OOP, this is often related to subclasses that override the parent method so that the more specific class might follow a different set of instructions. In my example, I use different barks of different breeds of doggos.
In practical terms, I've used this in past projects to account for the slight differences in the subclasses. For example, if we are calculating cost of an object, maybe one subclass is set in the US, and another class is specific to France.. we would use the subclass to change from dollars to euros in the France subclass and add an extra layer. We could do this with if-statements, but they might grow repetitive and confusing. Polymorphism is a cleaner way to implement something like this.

Good question.. I have a couple of directions - I want to do more tutorials and stuff, seems like most people want to see those. I also want to start talking about my research, make some videos that are less educational and more just about what you can do with CS. I want to inspire others!

Even my trainer was not able to make us understand that in 2 days, What you did in approx. 12 minutes. You have some serious skills!! Best of luck for future!!!! :)

I have been through a full stack developer bootcamp, and months of self-study. After watching this video, I finally feel like I REALLY understand Inheritance and Polymorphism. Great examples! Thank you!
This video was EXACTLY what I was looking for when trying to practice these concepts. Thank you so much
Clear, concise, pacey video and so helpful on these core concepts of OOP - deserves MANY more views! Thank you!
whoaa. ur so good at explaining everything in just a span of minutes. thank u so much. more videos like this, please
Was looking for someone who could explain this in a simple way, and found you after multiple trials of other sources. You just won a student, and I consider myself the privileged one here. Thanks a bunch.
Good job Kylie! Note: You don't need to cal the parent class's __init__ from the child class's __init__ if the child doesn't introduce any new attributes
It's the third time that I come back to this video to brush up on my knowledge of Python inheritance! Thanks for this amazing video.
I’m learning abit of python everyday and I’m really loving your videos! Super easy to understand and well explained!! Thank you soo much!! 🙏
Great video, thank you so much! I was completely tripped up on the connection between a sub __init__ and super().__init__ and it makes complete sense now. Also I love the dog examples!
I found Polymorphism a difficult concept to understand but after watching this video, I understood it perfectly well. Thnx for uploading great free content
This is a fantastic video with a very simple and straight forward example - keep up the good work!
OMG this is like the best video in explaining inheritance and polymorphism. So basically for inheritance you just include the name of parent class in the bracket of the subclass, then for polymorphism is just the idea of defining a method that's already present in the parent class but with different content.
Great work Kylie. Your Python series is well explained and the examples you use make your videos more interesting.
Best Example I have ever come across and I wish everybody to use Doggo examples 💖
I really like how you explained everything... keep up the great work, and keep teaching! I like your format quite a lot. :)
Your explanation of each of these topics was extremely clear and easy to understand! Excellent work. Also love the doggos
This video is exactly what I was looking for! You explain the concepts so clearly and using doggos really helps me to understand 🤣 thank you!
Thank you so much! Kylie!!! your examples on dog are wonderful!!
I was confused between the two but now I know the difference, thanks!
Thank you so much, you explained this in a super easy to understand way!
THANK YOU. Like the tone and pace of your voice. Easy to digest. Very precise and succinct as well. Subbed. ✌️
Awesome lesson! Very clearly explained. Thank you so much!
best tutorial, loved the doggo examples thnx
very clear video that allowed an old French man like me to finally understand polymorphism . Merci !
Thank you Kylie for such clear explaination using cute examples :)
The best explanation I've got on these subjects
Kylie, these videos are so good. They have really helped me a lot.
These were awesome watched all within a few days!
Excellent use of simple examples to explain inheritance and polymorphism :)
Amazing , glad that I found it . Good job and thank you
Thank you, you are really good at explaining and your examples are super helpful!!
Thanks for sharing the knowledge. It will now be a stepping stone for me. thanks a lot once again
You explain wonderfully! Thanks!
Best example!! Thank you!
You deserve a credit for those amazing videos :D Thanks so much
Nice!

Thanks Kylie I am really enjoying your pet programming
damnn this video was 100x better than I had thought it would be. Deserved a like for sure. Thanks!
thanks queen love the dog examples
Thank you for this great video! Helped me a lot.
So much clear explanation... We expect more videos like this...
I wish all programming videos on KZread were this quality
SUPER NICE KYLIE!!
Thankyou so much kylie.. ❤🧚♀️for the wonderful explanation
Thanks for your excellent explanation!
Most simple explanation of Polymorfism I've seen so far :) Better than with build in dunder method usual examples.

Glad it helped! Actually I gave a bad example I think. Usually when a child class has two parent classes, you dont want the "grandparent" class to be the same. Probably shouldve made a "Pet" class or something
thank you so much! much easier to understand than my prof
great video Kylie - so helpful
Seriously, best explanation ever :)
Thanks very much, explained much better than my uni!
Very good explanation..keep it up
Thanks for the vid Kylie!
thank you sooo soo much! you explain it so easily and in an interesting way.
Multiple videos watched on this topic and still couldn't understand because of all the jargon they used. Good video and thanks
Wonderful explanation!
you saved me! thank you so much 💓
Thanks love this was really helpful
thankyou so much kylie
Thank you so much!!
Amazing. It really helps
Very late comment but this video is absolutely amazing. Concise explanation given in an easy to digest manner. Thank you very much.
Great video.

Thank you so much ♥️♥️♥️♥️ you're the best
that was clear!
Thank you Mulan!
thank you i really needed a refresh
Thank you!
great video, thank you!
Kylie you're super amazing 💪😊
Thanks for great explanation. U deserve more subs :D
Great tutorial!
This was so cute. I love it. In my class, we kept using cats but I'm a dog person. lol
Wow! Thank you very much! That was a mater class @Kylie Ying
I like her cute little ponytail!!
This video was execellent
will you make more videos? I am eagerly waiting. You are so articulate and very good speaker with clarity in voice.
Nice content!
Nice Explanation

Thank you
this is what i needed :)
Thanks for the video, you explained it really well. I am trying to get my head around OOP, this sure did help. The only issue I can say is that you didn't mention a pug 🤣😝
Thank you for your great tutorial video... Please create more python tutorials for beginner...
Seeing the word 'doggo' used in your variable name made me scroll down from the video just to hit the like button. Also, thanks for explaining the concepts clearly!
Thank you 😭
Very nice video. 🙏
How can I like this video more than one time?🧠
