python通过服务器广播消息

Question

我正在尝试向子网广播消息，并且我将子网地址提供给服务器进行连接，并且客户端抛出错误，指出名称或服务未知且未接收到数据包。谁能告诉我如何向我的子网广播消息，以便客户端也可以获取该消息或数据包。完全在地址区域。我的主要疑虑是关于。哪个地址在客户端和服务器端给出。

我在客户端遇到的错误是：

sending
Traceback (most recent call last):
  File "/Threaded-server.py", line 11, in <module>
    sent=s.sendto(msg.encode(),address)
socket.gaierror: [Errno -2] Name or service not known
closing socket

Process finished with exit code 1

由于

的客户端

import socket
import sys
import json


connected = False

#connect to server
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((' ',10000))
connected = True

while connected == True:
    #wait for server commands to do things, now we will just display things
    data = client_socket.recv(1024)     
    cmd = json.loads(data) #we now only expect json    
    if(cmd['type'] == 'bet'):
        bet = cmd['value']
        print('betting is: '+bet)
    elif (cmd['type'] == 'result'):        
        print('winner is: '+str(cmd['winner']))
        print('payout is: '+str(cmd['payout']))
