Python(2.7)使用套接字和选择模块进行多次聊天(非阻塞代码)

import socket
import select

# 创建套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

# 绑定IP和端口
server_address = ('localhost', 8888)
server_socket.bind(server_address)

# 监听连接
server_socket.listen(5)

# 创建套接字列表
sockets_list = [server_socket]

while True:
    # 使用选择模块进行非阻塞监听
    read_sockets, _, _ = select.select(sockets_list, [], [])

    for sock in read_sockets:
        # 新的连接请求
        if sock == server_socket:
            client_socket, client_address = server_socket.accept()
            sockets_list.append(client_socket)
            print('新的连接：', client_address)

        # 已有连接的消息
        else:
            try:
                data = sock.recv(1024).decode()
                if data:
                    print('收到消息：', data)
            except:
                print('连接关闭')
                sock.close()
                sockets_list.remove(sock)
