Checking for an exception

[Steve D'Aprano]

What's the right/best way to test whether an object is an exception ahead of
time? (That is, without trying to raise from it.)

I have:

return (isinstance(obj, type) and issubclass(obj, BaseException)
        or isinstance(obj, BaseException))


Any better ideas?
