用python写一个tcp服务端

以下是一个简单的TCP服务器示例：

import socket

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

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

# 开始监听连接请求
server_socket.listen(1)
print('Server is listening on {}:{}'.format(*server_address))

while True:
    # 接受客户端连接
    client_socket, client_address = server_socket.accept()
    print('Received connection from {}:{}'.format(*client_address))

    try:
        # 接收客户端发送的数据
        data = client_socket.recv(1024)
        print('Received data from client: {}'.format(data))

        # 向客户端发送响应
        response = b'Hello, client!'
        client_socket.sendall(response)
    except Exception as e:
        print('Error occurred while processing client request: ', e)
    finally:
        # 关闭客户端连接
        client_socket.close()

此示例监听端口8888，接受客户端连接并返回“Hello, client!”响应。注意，此示例仅用于演示目的，实际服务器需要更复杂的逻辑来处理客户端请求。
