如何在Python中找到LAN的广播地址？

import socket
import fcntl
import struct

def get_interface_info():
    interfaces = socket.if_nameindex()
    interface_info = []
    for interface in interfaces:
        interface_name = interface[1]
        interface_address = socket.inet_ntoa(fcntl.ioctl(
            socket.socket(socket.AF_INET, socket.SOCK_DGRAM),
            0x8915,  # SIOCGIFADDR
            struct.pack('256s', interface_name[:15].encode('utf-8'))
        )[20:24])
        interface_info.append((interface_name, interface_address))
    return interface_info

def find_lan_broadcast_address():
    interface_info = get_interface_info()
    broadcast_addresses = []
    for interface in interface_info:
        interface_name = interface[0]
        interface_address = interface[1]
        if interface_address.startswith('127.'):
            continue  # 跳过本地回环接口
        broadcast_address = '.'.join(interface_address.split('.')[:-1]) + '.255'
        broadcast_addresses.append((interface_name, broadcast_address))
    return broadcast_addresses

broadcast_addresses = find_lan_broadcast_address()
for broadcast_address in broadcast_addresses:
    print(f"Interface: {broadcast_address[0]}, Broadcast Address: {broadcast_address[1]}")
