I suppose you mean b = foo() ?

The name of a class is in the attribute '__name__' of the class. The
class of an object is in the attribute '__class__' of the object.

>>> class Foo(object):
...     pass
...
>>> b = Foo
>>> b.__name__
'Foo'
>>> b = Foo()
>>> b.__class__.__name__
'Foo'

>>> help(dir)
Help on built-in function dir in module __builtin__:

dir(...)
    dir([object]) -> list of strings

    Return an alphabetized list of names comprising (some of) the attributes
    of the given object, and of attributes reachable from it:

    No argument:  the names in the current scope.
    Module object:  the module attributes.
    Type or class object:  its attributes, and recursively the attributes of
        its bases.
    Otherwise:  its attributes, its class's attributes, and recursively the
        attributes of its class's base classes.
