[Tutor] using variables as args

[Jerome Jabson]

Hello,

I'm trying to start a shell script with 4 arguments
from my python script. I'm having problems trying to
figure out the best way to do this. I'm using
variables as the arguments to the shell script. I want
to use popen3 to keep track of stdin, stdout, and err,
but from the docs I only see using spawnlp to use args
in starting an other process. Can someone help me
choice the best way to do this and the correct syntax
how?

Your help is much appreciated,
Jerome
