使用Python搜索具有MAC地址的主机

import socket
import fcntl
import struct

def get_mac_address(ip_address):
    # 创建一个socket对象
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    # 获取本地IP地址和子网掩码
    info = fcntl.ioctl(s.fileno(), 0x8915, struct.pack('256s', bytes(socket.gethostname(), 'utf-8')))[20:24]
    # 构造ARP协议报文
    arp_request = f"ARP request: who-has {ip_address} tell {info[0]}.{info[1]}.{info[2]}.{info[3]}"
    # 发送ARP协议报文
    response = os.popen(f"arping -c 1 -w 1 {ip_address}").read()
    # 解析ARP协议报文的响应
    if "Unicast reply from" in response:
        mac_address = response.split()[3]
        return mac_address
    else:
        return None
