今天捣鼓树莓派遇到到问题,用Python3获得本地IP地址，首先想到用socket.gethostbyname,不废话，直接上代码！

import socket
import fcntl
import struct
def get_ip_address(ethname):
    s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,
        struct.pack(b'256s',b'wlan0')
    )[20:24])
print get_ip_address("lo")
print get_ip_address("eth0")
print get_ip_address("wlan0")
