Right.   In addition, i'd suggest applying the short recpie in
<http://code.activestate.com/recipes/65287-automatically-start-the-debugger-on-an-exception/>
(i.e. add that snippet to sitecustomize.py) and learn a little bit of
pdb. This works everywhere and comes quite handy for inspecting code
right after something throws an exception.

Well, this is certainly a matter of taste.  I'd recommend using some
small, language independent programmers editor and some modern
distributed version control system  right at the beginning. Put your
code, even the smallest snippets,  under version control, make that a
habit.  Write small doctests for your code from the very beginning. Try
to construct your code so that it works equally well as a module and as
a standalone script   Don't start developing web applications, write
some small utilities for your own needs, first. 

Personally, I suggest SciTE and TortoiseHG on Windows, but that too is,
as I said, a matter of taste.

I don't edit code in IDLE, I just use it for interactive work. For
actual script editing, agreed (though I use git rather than hg), but
it really does help to have a way to *very* quickly test a line or two
of code.

I really REALLY like debugging with "eric"...

The need for a "python-aware" editor is the commonly held opinion, although the debate about which editor is endless.  I use Eclipse + PyDev only because I found it first and like it.

The only suggestion I would offer is to separate the business logic completely from the HTML request/response handler.  It makes it much easier to debug.  

Other than that, ditto to everyone else's response.

Fred.
