What software are you talking about here, it's certainly not Python 
versions as the most up to date are 2.7.3 and 3.3.0?

If you don't know what the [1] means you've got problems :)  I suggest 
you read the tutorial here first 
http://docs.python.org/tutorial/index.html then the subprocess module 
here http://docs.python.org/library/subprocess.html#module-subprocess, 
specifically 
http://docs.python.org/library/subprocess.html#subprocess-replacements
