Python socket实现文件传输的服务端与客户端

用python的socket模块实现的一个很简单的文件传输功能，不懂怎么写比较科学优雅，求各路大神指导

服务端：

#!/usr/bin/python 
#coding:utf-8 
import SocketServer 
import subprocess 
import string 
import time 
class MyTcpServer(SocketServer.BaseRequestHandler): 
    def recvfile(self, filename): 
        print "starting reve file!"
        f = open(filename, 'wb') 
        self.request.send('ready') 
        while True: 
            data = self.request.recv(4096) 
            if data == 'EOF': 
                print "recv file success!"
                break
            f.write(data) 
        f.close()
