 I think the more pythonic approach would be to define methods rather than classes, and this would not violate the above definition.  The class-based approach is needed in Java and has the advantage of explicitly setting out the required method in an abstract base class.

 Not quite the same as python [decorator syntax](https://docs.python.org/3/reference/compound_stmts.html#grammar-token-decorators) as in python you call the _decorated function_ and the decorating function is called first whereas the _decorating function_ must be called here.

 For instance the `PizzaStore` abstract class in this repo provides an abstract `create_pizza` interface for creating one product.
