[i[4][0] for i in socket.getaddrinfo(socket.gethostname(), None)]

对于linux，你可以使用hostname -I system命令的check_output，就像这样:

from subprocess import check_output
check_output(['hostname', '-I'])

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']

这是UnkwnTech的答案的变体——它提供了一个get_local_addr()函数，该函数返回主机的主LAN ip地址。我发布它是因为这增加了一些东西:ipv6支持，错误处理，忽略localhost/linklocal地址，并使用TESTNET地址(rfc5737)来连接。
