Let me repeat that that is historically wrong for Python, and illustrate why the term 'members' should not be used. From the 1.5 Language Reference, 3.2 Standard type hierarchy: "There are also some 'generic' special attributes, not listed with the individual objects: __methods__ is a list of the method names of a built-in object, if it has any; __members__ is a list of the data attribute names of a built-in object, if it has any."
This sentence was left untouched until 2.2. What's new 2.2 has "In previous versions of Python, there was no consistent way to discover what attributes and methods were supported by an object. There were some informal conventions, such as defining __members__ and __methods__ attributes that were lists of names, but often the author of an extension type or a class wouldn't bother to define them." This is a section on descriptors, but the real replacement is, I believe, dir().
