python socket实现多人聊天室

服务器端：

import socket
import select
import threading
import time

ss = socket.socket(
            socket.AF_INET, socket.SOCK_STREAM) 
host=socket.gethostname()#本地ip
port=9999
addr=(host,port)
ss.bind(addr)
ss.listen(5)#最多监听5个
print('runing server')

fd_name={}
SL=[]
SL.append(ss)

while True:
    r,w,e=select.select(SL,[],[])#python的select函数 select的三个列表分别表示发生变化的socket，没变化的，以及出错的 交给r,w,e
    for temp in r:
        if temp is ss:#ss变化说明有新连接
                connection,address = temp.accept()
                print('new connection address:',address)
                SL.append(connection)#将新连接加入SL
                name=connection.recv(1024).decode('utf-8')#记得将传来的比特流转成字符
                fd_name[connection]=name

                ###
