Thanks guys.  I went ahead and used subprocess.Popen as suggested and
that works fine.  Did something like:

import subprocess
subprocess.Popen("uptime", shell=True, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
stdout_value, stderr_value = subprocess.communicate()

The above worked great.  The 'uptime' was actually a fairly long
stretch of commands, and this allows me to check for STDERR and act
accordingly.  Thanks again for the help and suggestions.
