read results of cmd as list or string

[txwooley]

How would I execute a command and have it's output returned as a list or string? For example (in Linux):

os.system("iwconfig")

prints a list of wireless devices to stdout. How can I make Python see those results as a list or string so I can search for certain devices (like wlan0 for example) and their associated info?

[Gribouillis]

Use this code snippet. Write com = Command("iwconfig").run() .

[txwooley]

Which module contains "Command"? I can't find it in os, sys or subprocess. I get an error that "name 'Command' is not defined".

[Gribouillis]

It's defined here : http://www.daniweb.com/code/snippet257449.html

The return value of os.system depends on your OS, and the python documentation explicitly recommends using the subprocess module instead.

I tried that first. On Linux, os.system returns an integer (0 for True and oddly enough 246 for False). So it doesn't actually return the output, just the exit code.
