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)]

通过命令行utils产生“干净”输出的一个简单方法:

import commands
ips = commands.getoutput("/sbin/ifconfig | grep -i \"inet\" | grep -iv \"inet6\" | " +
                         "awk {'print $2'} | sed -ne 's/addr\:/ /p'")
print ips

它将显示系统上的所有IPv4地址。

在Linux上:

>>> import socket, struct, fcntl
>>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> sockfd = sock.fileno()
>>> SIOCGIFADDR = 0x8915
>>>
>>> def get_ip(iface = 'eth0'):
...     ifreq = struct.pack('16sH14s', iface, socket.AF_INET, '\x00'*14)
...     try:
...         res = fcntl.ioctl(sockfd, SIOCGIFADDR, ifreq)
...     except:
...         return None
...     ip = struct.unpack('16sH2x4s8x', res)[2]
...     return socket.inet_ntoa(ip)
... 
>>> get_ip('eth0')
'10.80.40.234'
>>> 

如果你正在寻找与本地主机IP地址127.0.0.1不同的IPV4地址，这里有一段简洁的python代码:

import subprocess
address = subprocess.check_output(['hostname', '-s', '-I'])
address = address.decode('utf-8') 
address=address[:-1]

也可以写成一行:

address = subprocess.check_output(['hostname', '-s', '-I']).decode('utf-8')[:-1]

即使您将localhost放在/etc/hostname中，代码仍然会给出本地IP地址。

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]);"

一个我不相信已经发布的版本。 我在Ubuntu 12.04上使用python 2.7进行测试。

找到这个解决方案:http://code.activestate.com/recipes/439094-get-the-ip-address-associated-with-a-network-inter/

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])

结果示例:

>>> get_ip_address('eth0')
'38.113.228.130'
