Thanks guys. That helped point me int he right direction.
with your advice on the subprocess module I stumbled upon this
posting:
http://www.velocityreviews.com/forums/t359866-subprocess-module.html
for anyone else that might be interested here is the solution. It
simply calls a perl script called add.pl that reads 2 numbers from
stdin and adds them together.
Thanks again for the help.

#!/usr/bin/env python
import subprocess
prog = "./add.pl"
args = "3 4"
app = subprocess.Popen
(prog ,stdout=subprocess.PIPE,stdin=subprocess.PIPE,stderr=subprocess.PIPE)
print "opened " + prog
#print app.stdout.read()
print "writing \'" + args + "\' to " + prog + " subprocess"
app.stdin.write(args)
app.stdin.write("\n")
print "wrote \'" + args + "\' to " + prog + " subprocess"
result = app.stdout.read()
result = result.rstrip('\n')
print "received: " + result
and here is the output:
./call_add.py
opened ./add.pl
writing '3 4' to ./add.pl subprocess
wrote '3 4' to ./add.pl subprocess
received: 7
