If you're prepared to accept URLs which use an extended path to indicate
arguments, one poosibility is to direct all requests to a "framework page"
which then calls the required Python functionality and traps any errors it
raises.

See, for example,

    http://www.webtechniques.com/archives/1998/02/kuchling/

in which Andrew Kuchling describes the basic technique.  This seems to give
you what you want.
