from netifaces import interfaces, ifaddresses, AF_INET
iplist = [ifaddresses(face)[AF_INET][0]["addr"] for face in interfaces() if AF_INET in ifaddresses(face)]
print(iplist)
['10.8.0.2', '192.168.1.10', '127.0.0.1']

我使用以下模块:

#!/usr/bin/python
# module for getting the lan ip address of the computer

import os
import socket

if os.name != "nt":
    import fcntl
    import struct
    def get_interface_ip(ifname):
        s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        return socket.inet_ntoa(fcntl.ioctl(
                s.fileno(),
                0x8915,  # SIOCGIFADDR
                struct.pack('256s', bytes(ifname[:15], 'utf-8'))
                # Python 2.7: remove the second argument for the bytes call
            )[20:24])

def get_lan_ip():
    ip = socket.gethostbyname(socket.gethostname())
    if ip.startswith("127.") and os.name != "nt":
        interfaces = ["eth0","eth1","eth2","wlan0","wlan1","wifi0","ath0","ath1","ppp0"]
        for ifname in interfaces:
            try:
                ip = get_interface_ip(ifname)
                break;
            except IOError:
                pass
    return ip

测试与windows和linux(和不需要额外的模块为那些) 用于在一个基于IPv4的局域网中的系统。

固定的接口名称列表不适用于最近的linux版本，这些版本已经采用了systemd v197关于可预测接口名称的更改，正如Alexander指出的那样。 在这种情况下，您需要手动使用系统上的接口名称替换该列表，或者使用其他解决方案，如netifaces。

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。

在Debian上(经过测试)，我怀疑大多数Linux ..

import commands

RetMyIP = commands.getoutput("hostname -I")

在MS Windows上(已测试)

import socket

socket.gethostbyname(socket.gethostname())

这个答案是我个人试图解决获得LAN IP的问题，因为socket.gethostbyname(socket.gethostname())也返回127.0.0.1。这种方法不需要Internet，只需要一个局域网连接。代码是为Python 3编写的。X但是可以很容易地转换为2.x。使用UDP广播:

import select
import socket
import threading
from queue import Queue, Empty

def get_local_ip():
        def udp_listening_server():
            s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
            s.bind(('<broadcast>', 8888))
            s.setblocking(0)
            while True:
                result = select.select([s],[],[])
                msg, address = result[0][0].recvfrom(1024)
                msg = str(msg, 'UTF-8')
                if msg == 'What is my LAN IP address?':
                    break
            queue.put(address)

        queue = Queue()
        thread = threading.Thread(target=udp_listening_server)
        thread.queue = queue
        thread.start()
        s2 = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s2.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
        waiting = True
        while waiting:
            s2.sendto(bytes('What is my LAN IP address?', 'UTF-8'), ('<broadcast>', 8888))
            try:
                address = queue.get(False)
            except Empty:
                pass
            else:
                waiting = False
        return address[0]

if __name__ == '__main__':
    print(get_local_ip())
