Encapsulation: Coupling data and the logic which acts on that data together in a concise, logical manner Polymorphism: The ability for one object to look-like and/or behave-like another. A good real-world example of this would be something like a directory iterator. Where is this directory?
compactability, melting behaviour and bioavailability, depend on their crystal form1. In silico crystal form selection has recently come much closer to realization because of the development of accurate and affordable free-energy calculations2,3,4. Here we redefine the state of the art, primarily b...
Adapting an interface of only one class to work with another seems a weak example of the GoF Adapter pattern. This pattern uses inheritance and polymorphism, so one would expect a good example to show multiple implementations of adapters for different adaptees. The best example I found is in...
Instead of an ellipsis, methods should have pass in the body. Class attributes such as pk and name can be defined using the @attribute decorator, but it will not work with Django models. You can now use the Product protocol to add type information. For example, in add_item(), you ...
Martin, more commonly known by his nickname Uncle Bob, who’s a well-respected figure in the software engineering world and one of the original signatories of the Agile Manifesto. In fact, he coined the term SOLID. The single-responsibility principle states that: A class should have only one...
Although the example of the data structure above is written in C++, those skilled in the art will recognize that equivalent data structures written in other languages may also be used. The major data fields of the block data structure fall into four categories including a graphical attributes fie...

As we can see, the relationship chain given in the above figure is quite natural and there is hardly any effort required on our part to define it. However, we are not always so fortunate to have that kind of natural inheritance hierarchy in real world problems. For example think of GDI+...
