如何在python中添加唤醒功能？

import RPi.GPIO as GPIO
import time

# 设置GPIO模式
GPIO.setmode(GPIO.BCM)

# 设置GPIO引脚
wake_pin = 18
GPIO.setup(wake_pin, GPIO.IN)

# 检测引脚状态变化
GPIO.add_event_detect(wake_pin, GPIO.RISING, callback=wake_up)

def wake_up(channel):
    print("Wake up!")

try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    GPIO.cleanup()

import socket
import struct

def send_wol(mac_address):
    # 将MAC地址转换为二进制格式
    mac_bytes = struct.pack('!6B', *[int(x, 16) for x in mac_address.split(':')])
    
    # 创建UDP套接字
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    
    # 构造魔术数据包
    magic_packet = b'\xff' * 6 + mac_bytes * 16
    
    # 发送魔术数据包
    sock.sendto(magic_packet, ('<broadcast>', 9))
    print("Wake-on-LAN packet sent to", mac_address)

# 示例MAC地址
mac_address = "00:11:22:33:44:55"
send_wol(mac_address)
