我是靠谱客的博主喜悦黑猫，最近开发中收集的这篇文章主要介绍Python socket实现简单聊天室，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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()
