如何获得给定网络接口的IP地址？

Question

在Python中有没有一个函数可以获取给定网络接口的IP地址？ 有没有命令行程序可以做到这一点？在

我想得到en1的IP地址。在

这是我机器上ifconfig的结果。在

$  ifconfig 
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    inet6 ::1 prefixlen 128 
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
    inet 127.0.0.1 netmask 0xff000000 
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 00:23:32:be:4e:90 
    media: autoselect
    status: inactive
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 00:23:6c:7e:3e:0c 
    inet6 fe80::223:6cff:fe7e:3e0c%en1 prefixlen 64 scopeid 0x5 
    inet 192.168.1.70 netmask 0xffffff00 broadcast 192.168.1.255
