Isn't that the very definition of "newbie"?  That's half a joke, but I
really don't think that programmers new to Python should be the
standard.  The problematic cases are those where even a relatively
experienced Python programmer needs to be told why an error is raised,
because it's too hard to figure out from background knowledge of the
language, you need to know about implementation internals.

I would love to see all automated systems become more informative with
errors!  One thing I like about Python the development community is
that people are doing something about it.  Slowly but surely ....

In general depending much on exception type is a hit-or-miss affair.
