[mod_python] How do I specifiy a script called from a html include?

I have  another problem.  I have a html that calls a python script like
this:

<!--#include file="prop.py/index?type=2" -->

Apache does not know how to handle it.  I get the following error:

unable to include "prop.py/index?type=2" in parsed
file /home/john/www/mydomain.com/condos.html

Do I need to specify some path before the script or am I missing a
Apache directive?
