how to run my own external command in python script

Question

I wanna to run my own non-system external commands in python.

Such as "sudo insteon on 23". Subprocess and os.system are designed for system calls.

Does anybody know how to do it?

Thanks

subprocess and os.system can be used to run any external command and typically do not run 'system calls', in fact you don't ever run system calls directly from a command line — ennuikiller, Apr 09 '13 at 19:32

You can use subprocess.Popen for this:

import shlex
import subprocess
proc = subprocess.Popen(shlex.split('sudo insteon on 23'))
proc.communicate()

Does `sudo insteon on 23` work from the command-line? – unutbu Apr 09 '13 at 19:52
Thank you very much. I just forgot to link the usb device. I run it on VirtualBox. – user2263305 Apr 09 '13 at 19:57
