X.__dict__

Dictionary used to store object X’s writable attributes.

I.__methods__

List of instance object I’s methods (name strings); it is

available on many built-in types.

*

I.__members__

List of instance object I’s data attributes (name strings);

it is available on many built-in types.

I.__class__

Class object from which instance I was generated. In

Version 2.2, this also applies to object types; most

objects will have a

__class__ attribute (e.g., [].__class_

_

== list == type([])).

C.__bases__

Tuple of class C’s base classes, as listed in C’s class state-

ment header.

X.__name__

Object X’s name as a string; for classes, the name in the

statement header; for modules, the name as used in

imports, or

"__main__" for the module at the top level of

a program (e.g., the main file run to launch a program).

Built-in Modules

Built-in modules are always available but must be imported

to be used in client modules. To access them, use one of

these formats:

•

import module, and fetch attribute names (module.name)

•

from module import name, and use module names unquali-

fied (

name)

•

from module import *, and use module names unqualified

(

name)

* _methods__ and __members__ are deprecated since Version 2.2; use the

built-in dir() function instead.
