稍微改进了使用IP命令的命令版本，并返回IPv4和IPv6地址:

import commands,re,socket

#A generator that returns stripped lines of output from "ip address show"
iplines=(line.strip() for line in commands.getoutput("ip address show").split('\n'))

#Turn that into a list of IPv4 and IPv6 address/mask strings
addresses1=reduce(lambda a,v:a+v,(re.findall(r"inet ([\d.]+/\d+)",line)+re.findall(r"inet6 ([\:\da-f]+/\d+)",line) for line in iplines))
#addresses1 now looks like ['127.0.0.1/8', '::1/128', '10.160.114.60/23', 'fe80::1031:3fff:fe00:6dce/64']

#Get a list of IPv4 addresses as (IPstring,subnetsize) tuples
ipv4s=[(ip,int(subnet)) for ip,subnet in (addr.split('/') for addr in addresses1 if '.' in addr)]
#ipv4s now looks like [('127.0.0.1', 8), ('10.160.114.60', 23)]

#Get IPv6 addresses
ipv6s=[(ip,int(subnet)) for ip,subnet in (addr.split('/') for addr in addresses1 if ':' in addr)]

你可以使用netifaces模块。类型:

pip install netifaces

在你的命令shell中，它会在默认的Python安装中安装自己。

然后你可以这样使用它:

from netifaces import interfaces, ifaddresses, AF_INET
for ifaceName in interfaces():
    addresses = [i['addr'] for i in ifaddresses(ifaceName).setdefault(AF_INET, [{'addr':'No IP addr'}] )]
    print '%s: %s' % (ifaceName, ', '.join(addresses))

在我的电脑上，它打印出:

{45639BDC-1050-46E0-9BE9-075C30DE1FBC}: 192.168.0.100
{D43A468B-F3AE-4BF9-9391-4863A4500583}: 10.5.9.207

这个模块的作者声称它应该在Windows、UNIX和Mac OS X上工作。

简单而甜蜜!

def getip():

    import socket
    hostname= socket.gethostname()
    ip=socket.gethostbyname(hostname)

    return(ip)

这与之前发布的答案非常相似，但我找不到任何与这种调用用法有关的答案。这是我用于ipv4的。对于ipv6，更改'。' in to ':' in

import socket
print next(i[4][0] for i in socket.getaddrinfo(
    socket.gethostname(), 80) if '127.' not in i[4][0] and '.' in i[4][0]);"

注意:这里没有使用标准库，但是非常简单。

$ PIP安装pif

from pif import get_public_ip
get_public_ip()

如果计算机有到Internet的路由，即使/etc/hosts没有正确设置，这也将始终工作以获得首选的本地ip地址。

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(('8.8.8.8', 1))  # connect() for UDP doesn't send packets
local_ip_address = s.getsockname()[0]
