版本：python 2.7.3
开发工具：IDLE (Python GUI)和Eclipse Pydev
服务器端代码：

# -*- coding: cp936 -*-
import socket  
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)#初始化socket 
sock.bind(("127.0.0.1", 8001))#绑定本机地址，8001端口
sock.listen(5)#等待客户连接 
while True:
    print "waiting client connection..."
    connection,address = sock.accept()#接收客户连接请求
    print "a client have connected..."
    while True:
        try:  
            connection.settimeout(5)  #设置超时时间
            buf = connection.recv(1024) #接收数据
            if buf == "1":  
               connection.send("you have send me 1!welcome to server!")
            elif buf=="2":
                connection.send("you have send me 2!I have recv!")
            elif buf=="3":
                connection.send("close the connection!")
                break
            else:  
               connection.send("unknow command!")  
        except socket.timeout:  
            print "time out"  
    connection.close()
    print "a client exit..."

客户端代码：

import socket  
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
sock.connect(("127.0.0.1", 8001))  
import time  
time.sleep(2)
while True:
    data=raw_input("input command:");
    sock.send(data)
    print sock.recv(1024)
    if data=="3":
       break
sock.close()
