一个python服务器代码

下面是一个简单的python服务器代码：

import socket

HOST = 'localhost'
PORT = 8888

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

# 绑定主机和端口
server_socket.bind((HOST, PORT))

# 监听客户端连接
server_socket.listen()

print(f"Server is listening on {HOST}:{PORT}...")

while True:
    # 等待客户端连接
    client_socket, client_address = server_socket.accept()

    print(f"Client {client_address} connected.")

    # 接收客户端消息
    data = client_socket.recv(1024)

    if data:
        # 处理客户端消息
        response = b"Hello, world!"
        # 发送响应消息给客户端
        client_socket.sendall(response)

        print(f"Sent response to client {client_address}")

    # 关闭客户端连接
    client_socket.close()

这个服务器会监听本地8888端口上的连接，并在接收到客户端消息后回复“Hello, world!”。
