execute commands and return output

[billiejoex]

Thank you for your help but I'm searching a different way.
Moreover it doesn't work always (for exaple: try a 'dir' command).
Because of I'm implementing a remote shell  the 
[[os.popen('command').read()]] rapresents the best for me because it can 
also accepts arguments direclty  (for example: 
os.popen('netstat -a -n -o').read() and this is a great advantage.
I was looking at sys.stdout and sys.stderr. Can they be helpful?

Cheers
