 | 
 |     http://www.xyz.com/program.py?dothis
 | 
 | or
 | 
 |     http://www.xyz.com.program.py?dothat
 | 
 | and have the Python program determine what to do when it receives either
 | dothis or dothat.

if that is all you want to do, the easiest way would probably be:

 import os

 if os.environ["QUERY_STRING"] == "dothis":
         dothis()
 elif os.environ["QUERY_STRING"] == "dothat":
         dothat()
..etc..

you probably want to use the cgi module if you want
to pass more variables to the script, like
http://www.xyz.com/program.py?do=this&usefulvariable=23
