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

import socket
socket.gethostbyname(socket.gethostname())

This won't work always (returns 127.0.0.1 on machines having the hostname in /etc/hosts as 127.0.0.1), a paliative would be what gimel shows, use socket.getfqdn() instead. 

Answer 2

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

s.connect(("8.8.8.8", 80))

print(s.getsockname()[0])

s.close()
