There are several; for some reason I don't really understand, there are
multiple Python/PostgreSQL modules.  Most of them will support the standard
DB-API described in PEP 249.  Personally I use PygreSQL with Quixote as the
web framework.

Note that I'm one of the developers on a Python web framework called Quixote
(, so my answers are slanted in that direction.  If you're in
the Washington DC area, I'll be giving a Quixote tutorial next weekend at a
Linux user group meeting; see for meeting details.

mxDateTime has an extensive parsing module.  There's a PEP for adding date
parsing to core Python, but it may not get done for 2.4.

It embeds a Python interpreter in the Apache daemon, so you can intersperse
Python processing in Apache's request processing.  There's going to be a
mod_python tutorial at the upcoming PyCon conference; again, if you're in
the DC area you might consider going in order to talk to existing Python/web

Note that embedding the interpreter in Apache isn't a requirement; you can
also run applications using SCGI, or FastCGI instead.  You'd have to carry
out benchmarks to see which one ends up running fastest for your

There are various templating packages available for Python, such as Cheetah
(vaguely PHPish), ZPT (XML-based), or PTL (part of Quixote). Personally I
don't find embedding Python code in HTML to be a good idea; it's too
difficult to refactor, and PTL has various convenient features for
automatically quoting HTML.

One of the upsides of using Python is that many more non-Web-related
packages have been written for it.  Scientific programming is a significant
application domain for Python, so several graphing packages have been
written. You could use Reportlab for PDF generation, Chaco, Gnuplot, or Gist
for graphing, or the Python Imaging Library for generating PNGs/JPGs.
