I was thinking the same thing, and you could even write a fancy __getattrr__, so you could do: raise ExceptionMaker.BadStuffErrror(details, plus, more_details) But here's where I am still completely confused. In order to catch that Exception, you need know about it -- it's name, what parameters it uses, etc. And that will be potentially very far from the code that creates it. And what if you want to raise the same (or similar) exception somewhere else? The OP has stated that all making an Exception class does is create a name -- which is true (though the other thing it does is put that name in a class hierarchy) -- but the thing is -- that's very useful! In fact, I can't see how you could do this at all without creating a name somewhere that it could be accessed from elsewhere. -CHB > _______________________________________________ > Python-ideas mailing list -- [email protected] > To unsubscribe send an email to [email protected] > https://mail.python.org/mailman3/lists/python-ideas.python.org/ > Message archived at > https://mail.python.org/archives/list/[email protected]/message/M7LP4OMSEU47MBWX75KGBM7343SH5XGI/ > Code of Conduct: http://python.org/psf/codeofconduct/ > -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
