如何使用Python 3创建TCP服务器？

import socket

# 创建TCP服务器
def create_tcp_server(host, port):
    # 创建socket对象
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    # 绑定地址和端口
    server_socket.bind((host, port))
    
    # 监听连接
    server_socket.listen(1)
    
    print("服务器已启动，等待客户端连接...")
    
    while True:
        # 接受客户端连接
        client_socket, client_address = server_socket.accept()
        print("客户端已连接：", client_address)
        
        # 接收客户端发送的数据
        data = client_socket.recv(1024)
        print("接收到客户端的数据：", data.decode())
        
        # 发送响应给客户端
        response = "Hello, client!"
        client_socket.sendall(response.encode())
        
        # 关闭连接
        client_socket.close()
        print("客户端连接已关闭")

# 主函数
if __name__ == "__main__":
    host = "localhost"  # 主机地址
    port = 8888  # 端口号
    
    create_tcp_server(host, port)
