oop - What is the definition of interface in object oriented . . . An interface promises nothing about an action! The source of the confusion is that in most languages, if you have an interface type that defines a set of methods, the class that implements it "repeats" the same methods (but provides definition), so the interface looks like a skeleton or an outline of the class
What is the difference between an interface and abstract class? An interface is a good example of loose coupling (dynamic polymorphism dynamic binding) An interface implements polymorphism and abstraction It tells what to do but how to do is defined by the implementing class
oop - How do I implement interfaces in python? - Stack Overflow 236 Implementing interfaces with abstract base classes is much simpler in modern Python 3 and they serve a purpose as an interface contract for plug-in extensions Create the interface abstract base class:
Inheriting comments from an interface in an implementing class? The bright side is that Visual Studio validates copied elements, so it is much easier to keep documentation and code in sync with interface base class, etc (for example names of arguments, names of type parameters, etc)
oop - When to use an interface instead of an abstract class and vice . . . An Interface is more of a high level architectural tool (which becomes clearer if you start to grasp design patterns) - an Abstract has a foot in both camps and can perform some of the dirty work too Why use one over the other? The former allows for a more concrete definition of descendants - the latter allows for greater polymorphism
