What is the difference between mixins and abstract classes?

Can you explain the difference between mixins and abstract classes?

Sure! Mixins are a way to add functionality to classes by including methods from other classes, while abstract classes are templates that define methods that must be implemented by subclasses.

Can you give me an example of how mixins work?

Absolutely! In Python, you can create a mixin class with a method, and then include that mixin in other classes to add that method's functionality.

What about abstract classes? How do they differ in usage?

Abstract classes are used to define a common interface for subclasses. They can have both abstract methods (without implementation) and concrete methods (with implementation). Subclasses must implement the abstract methods.

Are there any programming languages that don't support mixins?

Yes, not all programming languages support mixins. For example, languages like Java do not have built-in support for mixins, but they can achieve similar functionality through interfaces and composition.
