Attribute Description
__bases__   A tuple that contains base classes from which the class directly inherits.
If the class does not inherit from other classes, the tuple is empty.
[Note: We discuss base classes and inheritance in Chapter 9, Object-
Oriented Programming: Inheritance.]
__dict__     A dictionary that corresponds to the class’s namespace. Each keyvalue
pair represents an identifier and its value in the namespace.
__doc__ A class’s docstring. If the class does not specify a docstring, the value
is None.
__module__ A string that contains the module (file) name in which the class is
defined.
__name__   A string that contains the class’s name.
