Summary: can't getattr() attribute shown by dir()

Initial Comment:
I occasionally write introspective code that does
something like:

for attr in dir(obj):
    print attr, getattr(obj, attr)

I ran into a problem with it, though:

>>> ArithmeticError.__init__
<unbound method ArithmeticError.__init__>
>>> dir(ArithmeticError.__init__)
['__call__', '__class__', '__cmp__', '__delattr__',
'__dict__', '__doc__', '__get__', '__getattribute__',
'__hash__', '__init__', '__name__', '__new__',
'__reduce__', '__repr__', '__setattr__', '__str__',
'im_class', 'im_func', 'im_self']
>>> '__dict__' in dir(ArithmeticError.__init__)
1
>>> ArithmeticError.__init__.__dict__
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'builtin_function_or_method' object has
no attribute '__dict__'
