另一个变体的前面的答案，可以保存到一个名为my-ip-to的可执行脚本:

#!/usr/bin/env python

import sys, socket

if len(sys.argv) > 1:
    for remote_host in sys.argv[1:]:
        # determine local host ip by outgoing test to another host
        # use port 9 (discard protocol - RFC 863) over UDP4
        with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as s:
            s.connect((remote_host, 9))
            my_ip = s.getsockname()[0]
            print(my_ip, flush=True)
else:
    import platform

    my_name = platform.node()
    my_ip = socket.gethostbyname(my_name)
    print(my_ip)

它需要任意数量的远程主机，并打印出本地ip，逐个到达它们:

$ my-ip-to z.cn g.cn localhost
192.168.11.102
192.168.11.102
127.0.0.1
$

并在没有给出arg时打印best-bet。

$ my-ip-to
192.168.11.102

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'
>>>

要获取ip地址，可以直接在python中使用shell命令:

import socket, subprocess

def get_ip_and_hostname():
    hostname =  socket.gethostname()

    shell_cmd = "ifconfig | awk '/inet addr/{print substr($2,6)}'"
    proc = subprocess.Popen([shell_cmd], stdout=subprocess.PIPE, shell=True)
    (out, err) = proc.communicate()

    ip_list = out.split('\n')
    ip = ip_list[0]

    for _ip in ip_list:
        try:
            if _ip != "127.0.0.1" and _ip.split(".")[3] != "1":
                ip = _ip
        except:
            pass
    return ip, hostname

ip_addr, hostname = get_ip_and_hostname()

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]);"

import socket
socket.gethostbyname(socket.gethostname())

这并不总是有效(在/etc/hosts主机名为127.0.0.1的机器上返回127.0.0.1)，gimel显示的是一个缓和的方法，使用socket.getfqdn()代替。当然，您的机器需要一个可解析的主机名。
