2.1.8 Special Attributes

The implementation adds a few special read-only attributes to several object types, where they are relevant:

__dict__
A dictionary or other mapping object used to store an object's (writable) attributes.

__methods__
List of the methods of many built-in object types, e.g., [].__methods__ yields ['append', 'count', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']. This usually does not need to be explicitly provided by the object.

__members__
Similar to __methods__, but lists data attributes. This usually does not need to be explicitly provided by the object.

__class__
The class to which a class instance belongs.

__bases__
The tuple of base classes of a class object.
