In this video, I go over abstract base classes.
Included in the lesson is how to create a basic abstract base class with abstract methods as well as the basis for a powerful plugin system.

Can you explain how descripters in python works ?

@JakeCallahan Жыл бұрын

I sure can. In fact, I'll move that up to be the subject of my next video.

@@JakeCallahancame here after your descriptor video.. you are a blessing... to stick to your word and getting it done so quick.. Looking forward to more of such great videos from you I would just request one thing to start with a real life use case as to why we would prefer these concepts implemented before jumping on to how it works

@halfbakedthoughts4150 thank you for the kind words and feedback. I like to build up towards the more practical examples, but I can definitely see how showing practical could be motivational.

Excellent tutorial, @JakeCallahan. You've covered the material beautifully, especially the "register" functionality. I've read the official docs and had no idea what it was talking about 😅. Now it's crystal clear! Thank you !!

What's the difference between abstractmethod and abc.abstractclassmethod?

@JakeCallahan 3 ай бұрын

The second is used for methods decorated with @classmethod. If you're unsure what those are, check out my video in this playlist on Basic Classes.

@@JakeCallahan ah... so it's just @abstractmethod @classmethod in a single decorator

@JakeCallahan 2 ай бұрын

You're correct! However, abstractclassmethod was deprecated almost immediately after being introduced because they enabled the classmethod decorator to decorate an abstractmethod. So to do this, just stack a classmethod decorator on top of the abstractmethod decorator.

@@JakeCallahan I see but seeing that you use it, I guess people still widely use the decorator?

While you can use it for now, it will be removed in the future, so best to avoid it.
