Difference between Abstract Class and Interface in Django

In Django, the main difference between an abstract class and an interface lies in their implementation and usage.

An abstract class in Django is a class that cannot be instantiated and is used as a blueprint for other classes. It may contain abstract methods that must be implemented by its subclasses. Abstract classes in Django are typically used to provide common functionality to multiple classes without creating instances of the abstract class itself.

On the other hand, an interface in Django is a type that defines a contract for implementing classes. It specifies a set of methods that a class must implement, without providing any method implementations. Classes can implement multiple interfaces in Django, which allows for flexibility in designing and structuring the code.

Overall, understanding the difference between abstract classes and interfaces in Django is essential for creating flexible and scalable applications that adhere to object-oriented programming principles.
