an attribute that specifies a non-unique characteristic of a particular entity instance

(property) A data structure that describes the attributes of a given property, whether primitive or not. Not all properties need descriptors of their own; if a descriptor is not defined, the one for the property default-property is used.

also called attribute

Any new-style object that defines the methods __get__(), __set__(), or __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 classes.

A term used with a brand name to communicate an informational attribute (e.g., variant, function, occasion or target segment) about a specific offer.
