在python中的不同LAN之间发送数据

import socket

    s.settimeout(5)  # 设置超时时间为5秒
    s.connect(('目标IP', 目标端口))

    print("连接超时，请检查网络设置或目标主机状态。")

# 发送方
data = "Hello, World!"
s.sendall(data.encode())

# 接收方
received_data = b""
while True:
    packet = s.recv(1024)
    if not packet:
        break
    received_data += packet
print(received_data.decode())

print("服务器已启动，等待连接...")

while True:
    client_socket, addr = server_socket.accept()
    print(f"连接来自: {addr}")
