It sounds to me like you're doing this the hard way -- if you want an 
exception object, you should be able to simply construct it, e.g.:

dir(TypeError())

This will give me a dir on an *instance* of TypeError, as opposed to:

dir(TypeError)

which will just give me the class info.

Of course, I might want to read:

TypeError().__doc__

(which I find more useful than just knowing the attributes, which are pretty 
much the same for all built-in exceptions).

Hope this helps,
Terry
