2.2.10 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__`
  Deprecated since release 2.2. Use the built-in function `dir()` to get a list of an object's attributes. This attribute is no longer available.

`__members__`
  Deprecated since release 2.2. Use the built-in function `dir()` to get a list of an object's attributes. This attribute is no longer available.

`__class__`
  The class to which a class instance belongs.

`__bases__`
  The tuple of base classes of a class object. If there are no base classes, this will be an empty tuple.
