Although class attributes may seem like global variables, each class attribute resides in the namespace of the class in which it is created. Class attributes should be initialized once (and only once) in the class definition. A class’s class attributes can be accessed through any object of that class. A class’s class attributes also exist even when no object of that class exists. To access a class attribute when no object of the class exists, prefix the class name, followed by a period, to the name of the attribute.
