用python获取本机的ip地址

#!/usr/bin/python
#coding=utf-8


import socket
import fcntl
import struct

def get_ip_address(ifname):
     s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
         s.fileno(),
         0x8915, # SIOCGIFADDR
         struct.pack('256s', ifname[:15])
    )[20:24])


if __name__ == '__main__':
    print get_ip_address('lo')#环回地址
    print get_ip_address('eth0')#主机ip地址
