Class attribute

In Object-oriented programming(OOP), classes and objects have attributes. Attributes are data stored inside a class or instance and represent the state or quality of the class or instance . In short, attributes store information about the instance.

Attributes and methods are basically variables and functions that belongs to the class . These are often referred to as “class members”. A class is a user-defined data type that we can use in our program, and it works as an object constructor, or a “blueprint” for creating objects.

Class attributes are variables of a class that are shared between all of its instances . They differ from instance attributes in that instance attributes are owned by one specific instance of the class only, and ​are not shared between instances.
