First, we import socket and os libraries from python libraries.

import socket
import os

then we find our ip address with the code below.

gw = os.popen("ip -4 route show default").read().split()
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect((gw[2], 0))
ipaddr = s.getsockname()[0]
gateway = gw[2]
host = socket.gethostname()
print ("IP:", ipaddr, " GW:", gateway, " Host:", host)
