Didn't this get answered on the python tutor mailing list within the 
last couple of hours?  What's with it with you?

A couple of things I would like to point out here:

1.) It is possible that Debashish sent similar questions to multiple
mailing lists in the hopes to maximize the chance of getting a response.
It may only "appear" that this thread was started after having the question
answered on another mailing list because of the delays that are notorious
on this list.  I suspect he sent both emails at around the same time, but
the python tutors list processed it faster than the matplotlib-users list.

Therefore...

2.) I would like to make sure that this mailing list remains a welcoming
forum for all users, and for all of us to understand that people have
different mailing habits that we may not be familiar with.  Therefore,
gentle reminders of mailing decorum (such as reminders to bottom-post)
should be the response, not chastising.

-- Debashish,

We are more than happy to help you.  Please keep your question to a single
mailing list at a time.  The users on the mailing list will let you know if
you should direct your question elsewhere.  In the case of your problem, it
is not matplotlib, but mayavi.  Hopefully, you have been directed to the
mayavi mailing list.

Cheers!

Please accept my apologies if I breached protocol but there are five 
threads from the OP on the Python tutor mailing list, each of which has 
had one or more replies.  Two of them don't actually ask a question, the 
above being one, and the OP hasn't had the courtesy to reply to anyone 
with a thank you or anything else.

Cheers.

Mark,

That may be the case, but he has only posted one other question before on
*this* mailing list.  I do not frequent the python tutors list, and I do
not know how that list is run.  I don't even "run" this list, either, so I
shouldn't be considered a moderator.  However, as a fellow poster, I would
rather leave emails unanswered if we don't have anything constructive to
say, IMHO.

Cheers!

Correct, four minutes after posting it on the Python tutor mailing list. 
  Presumably the people over there were discourteous for not answering 
quickly enough?  Of course if you're happy to see people just slap a 
Python traceback here without even asking a question and presumably 
expect somebody to give a positive response then that's fine by me, but 
to do it in two separate places is just plain rude as far as I'm 
concerned and needs responding to.  It seems as if the two of us think 
differently so I think it best if we agree to disagree and leave it at 
that.  Is this ok with you?

I am more of a live-and-let-live kind of person.  I don't disagree that it
is rude.  Certainly, if there is an apparent need to teach a user how to
provide more useful questions and not spam the lists, then let's do so in a
teaching manner.  However, if the person continues to not provided useful
questions, then what can you do?  If you want to vent, vent at stuffed
animal.

I welcome all on this list regardless of past "transgressions", and I want
to make sure everyone feels welcomed. As far as I am concerned, nothing
more needs to be said.
