The current exception hierarchy isn't too far from what you suggest. We just got the names wrong. That is, there is a base class, StandardException, that captures most exceptions other than MemoryError, SystemError, and KeyboardInterrupt. If we renamed that Exception, then we'd be 90% of the way there. You could also change your code, right now, to say "except StandardError:" and avoid the problem entirely.

when was that changed?

Python 2.4a3 (#1, Sep 3 2004, 11:32:03)

StandardException Traceback (most recent call last): File "", line 1, in ? NameError: name 'StandardException' is not defined StandardError <class exceptions.StandardError at 0x401a329c> issubclass(MemoryError, StandardError) True issubclass(KeyboardInterrupt, StandardError) True issubclass(SystemExit, StandardError) False issubclass(StopIteration, StandardError) False issubclass(ImportError, StandardError) True
