I am assuming your platform is Linux.  If I am incorrect then
ignore this post.

The code below reads /proc/net/route to obtain the gateway and
then prints it.  It can be run as-is from a terminal.

#!/usr/bin/env python

import socket
import struct

def get_gateway_ip():
    try:
        with open("/proc/net/route", "r") as f:
            route = f.readlines()
    except IOError:
        return None
    for line in route:
        fields = line.strip().split()
        if fields[1] != "00000000" or not int(fields[3], 16) & 2:
            continue
        gateway = socket.inet_ntoa(struct.pack("<L", int(fields[2], 16)))
        break
    return gateway

print get_gateway_ip()
