如何在python中从服务器更新客户端标签？

import socket

# 创建一个TCP/IP socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定服务器的IP地址和端口号
server_address = ('localhost', 8888)
server_socket.bind(server_address)

# 监听客户端连接
server_socket.listen(1)

while True:
    print('等待客户端连接...')
    client_socket, client_address = server_socket.accept()
    print('客户端已连接:', client_address)

    try:
        # 接收客户端发送的数据
        data = client_socket.recv(1024)
        if data:
            # 更新客户端标签
            new_label = 'New Label'
            client_socket.sendall(new_label.encode())
    finally:
        # 关闭客户端连接
        client_socket.close()

import socket

# 创建一个TCP/IP socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 服务器的IP地址和端口号
server_address = ('localhost', 8888)

# 连接服务器
client_socket.connect(server_address)

try:
    # 发送数据到服务器
    message = 'Update Label'
    client_socket.sendall(message.encode())

    # 接收服务器返回的数据
    new_label = client_socket.recv(1024)
    print('更新后的标签:', new_label.decode())
finally:
    # 关闭客户端连接
    client_socket.close()
