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

If you're looking for an IPV4 address different from your localhost IP address 127.0.0.1, here is a neat piece of python codes:

import subprocess
address = subprocess.check_output(['hostname', '-s', '-I'])
address = address.decode('utf-8') 
address=address[:-1]

Which can also be written in a single line:

address = subprocess.check_output(['hostname', '-s', '-I']).decode('utf-8')[:-1]

Even if you put localhost in /etc/hostname, the code will still give your local IP address.
