聊天应用程序中的套接字错误尝试对非套接字的内容执行错误操作

Question

我正在尝试在python上创建一个简单的聊天应用程序。我创建了client.py和server.py，并参考了这个site

服务器运行正常，而客户端代码运行时出错为

解决此问题我已重置winsock并尝试从this site重新安装tcp / ip

如何解决此问题 的 client.py

import socket, select, string, sys

def prompt() :
    sys.stdout.write('<You> ')
    sys.stdout.flush()

#main function
if __name__ == "__main__":

    if(len(sys.argv) < 3) :
        print 'Usage : python telnet.py hostname port'
        sys.exit()

    host = sys.argv[1]
    port = int(sys.argv[2])

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(2)

    # connect to remote host
    try :
        s.connect((host, port))
    except :
        print 'Unable to connect'
        sys.exit()

    print 'Connected to remote host. Start sending messages'
    prompt()

    while 1:
        socket_list = [sys.stdin, s]

        # Get the list sockets which are readable
        read_sockets, write_sockets, error_sockets = select.select(socket_list , [], [])

        for sock in read_sockets:
            #incoming message from remote server
            if sock == s:
                data = sock.recv(4096)
                if not data :
                    print '\nDisconnected from chat server'
                    sys.exit()
                else :
                    #print data
                    sys.stdout.write(data)
                    prompt()

            #user entered a message
            else :
                msg = sys.stdin.readline()
                s.send(msg)
                prompt()
