[GCC 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036]] on

Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.gethostbyname(socket.gethostname())
'127.0.0.2'

It's a valid IP of my computer, but not the one you wanted. You could 
have written this one from memory (well I would have written 
127.0.0.1, which is also valid).  

Parsing the output from ifconfig would work for my computer. 


Kind regards,
