本文实例为大家分享了Python socket实现简单聊天室的具体代码，供大家参考，具体内容如下

服务端使用了select模块，实现了对多个socket的监控。客户端由于select在Windows下只能对socket使用，所以使用了多线程来实现对客户端输入和socket连接的同时监控。注意这里的socket设置为了非阻塞。这样就实现了在一个线程中同时进行socket的接收和发送。

服务器代码：

# -*- coding: utf-8 -*-
import socket,select
connection_list = []
host = ''
port = 10001
def board_cast(sock,message):
 for socket in connection_list:
  if socket != server_sock and socket != sock:
   try:
    socket.send(message)
   except:
    socket.close()
    print str(socket.getpeername())+' is offline'
    connection_list.remove(socket)
server_sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server_sock.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
server_sock.setblocking(0)
server_sock.bind((host,port))
server_sock.listen(10)
connection_list.append(server_sock)
while 1:
 readable,writable,error = select.select(connection_list,[],[])
 for sock in readable:
  if sock == server_sock:
   connection,connection_add = sock.accept()
   message = str(connection_add)+'enter room'
   board_cast(connection,message)
   print connection_add,'%s connect'
   connection_list.append(connection)
  else:
   try:
    date = sock.recv(1024)
    print date
    board_cast(sock,'('+str(sock.getpeername())+') :'+date)
   except:
    message2 = str(sock.getpeername())+ 'is offline'
    board_cast(sock,message2)
    print str(sock.getpeername())+ ' is offline'
    sock.close()
    connection_list.remove(sock)
    continue

客户端代码：

# -*- coding: utf-8 -*-
import socket,threading,time
flag = 0
date = ''
lock = threading.Lock()
host = 'localhost'
port = 10001
client_sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client_sock.setblocking(0)
class Mythread1(threading.Thread):
 def __init__(self):
  threading.Thread.__init__(self)
 def run(self):
  global flag, date
  while 1:
   date = raw_input()
   if len(date):
    lock.acquire()
    flag = 1
    lock.release()
class Mythread2(threading.Thread):
 def __init__(self):
  threading.Thread.__init__(self)
 def run(self):
  global flag
  global date
  while 1:
   try:
    buf = client_sock.recv(1024)
    if len(buf):
     print buf
   except:
    pass
   if flag:
    try:
     client_sock.send(date)
    except socket.error, e:
     print e
    lock.acquire()
    flag = 0
    lock.release()
try:
 client_sock.connect((host,port))
 print"连接成功"
except socket.error,e:
 print e
t1 = Mythread1()
t2 = Mythread2()
t1.start()
t2.start()
