Finding local IP addresses using Python's stdlib

Question

How can I find local IP addresses (i.e. 192.168.x.x or 10.0.x.x) in Python platform independently and using only the standard library?

Answer 1

I use this on my ubuntu machines:

import commands
commands.getoutput("/sbin/ifconfig").split("\n")[1].split()[1][5:]

This doesn't work.
