Yes, that would have been better.
I would be interested to know which response of Steven's you thought
insulting. In reviewing the correspondence the only "insults" I see from
him appear to be (correct) assertions that your code doesn't work under
certain circumstances. Your refutation that "that's probably because it
can't be ran in the interactive terminal" ignores his attempt to help
you avoid real problems, and bypasses his attempt to find out why you
felt it was necessary to obtain the names of things which sometimes
don't have names.
While I have no problem with you ignoring good advice I would prefer it
if you didn't tell knowledgeable and helpful Python programmers to "just
shut up until you know what the hell you are talking about" when they
have already provided long-term evidence by their helpfulness on c.l.py
that they do indeed know what they are talking about. That doesn't
advance any dialog, and isn't normally allowed in the kindergarten
playground, let alone in what purports to be a technical dialog between
So in future, unless you are *really* sure you are being personally
insulted for no good reason, it would be a much more adult response to
maintain a dignified silence.
Or do you regard this message as insulting also?
