You can get the class by
>>> class A(object):
pass
>>> locals()['A']
<class __main__.A at 0xf0cb90>
and you can get the class dictionary (methods and class attributes) like
>>> locals()['A'].__dict__.keys()
['__dict__', '__module__', '__weakref__', '__doc__']
>>>
but since python is a dynamic language it's only possible to know what
attributes are present by looking at instances. eg.
>>> a = A()
>>> a.__dict__.keys()
[]
>>> a.foo = 1
>>> a.__dict__.keys()
['foo']
>>> a.foo
1
