descriptor
Any *new-style* object that defines the methods :meth:`__get__`,

+ :meth:`__set__`, or :meth:`__delete__`. When a class attribute is a
descriptor, its special binding behavior is triggered upon attribute
- lookup. Normally, writing *a.b* looks up the object *b* in the class
- dictionary for *a*, but if *b* is a descriptor, the defined method gets
- called. Understanding descriptors is a key to a deep understanding of
- Python because they are the basis for many features including functions,
- methods, properties, class methods, static methods, and reference to super
