python获取本地ip地址的方法

#_*_coding:utf8_*_

#以下两种方法可以在ubuntu下或者windows下获得本地的IP地址
import socket

# 方法一
localIP = socket.gethostbyname(socket.gethostname())
print ("local ip address: %s"%localIP)

ipList = socket.gethostbyname_ex(socket.gethostname())

# 循环打印
for i in ipList:
    if i != localIP:
        print "Other ip address: %s"%i

# 方法二
print("获得本地IP地址的第二中方法")

ipname = socket.getfqdn(socket.gethostname())
myaddress = socket.gethostbyname(ipname)
print myaddress

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])
