help() on an Exception class lists the method resolution order (effectively the
inheritance hierarchy).
E.g. help(ArithmeticError) displays inter alia:
Method resolution order:
ArithmeticError
StandardError
Exception
BaseException
__builtin__.object
Would it be possible for it also display the Python built-in SUBclasses of the
class? E.g. in the same example something like:
Built-in subclasses:
FloatingPointError
OverflowError
ZeroDivisionError
This may seem pointless to grizzled old Python veterans who (maybe) know the
inheritance hierarchy backwards, but for those of us with less experience I
think it would be helpful, e.g.
(1) It would help to track down an Exception whose name you have forgotten.
(2) It would sometimes be illuminating, e.g. LookupError might be a bit obscure
at first, until you see that it is the superclass of the familiar IndexError
and KeyError.
Sorry, I'm not sure if I should send this sort of thing to Python-Ideas or
Python-Dev, so please let me know gently which one I should (not) have sent it
to.
Best wishes
