账号：huge 密码：file

提示：phone that evil

点击按键5，打开 http://www.pythonchallenge.com/pc/phonebook.php

 也就是给了一个电话本，需要打电话被evil

import xmlrpc.client

with xmlrpc.client.ServerProxy("http://www.pythonchallenge.com/pc/phonebook.php") as pb:
    print(pb.system.listMethods())
    print(pb.system.methodHelp('phone'))
    print(pb.phone("eval"))

得到提示：

['phone', 'system.listMethods', 'system.methodHelp', 'system.methodSignature', 'system.multicall', 'system.getCapabilities']
Returns the phone of a person
He is not the evil

那谁是evil？想起12关第四张图的返回信息 Bert is evil!

修改脚本，打电话给Bert

import xmlrpc.client

with xmlrpc.client.ServerProxy("http://www.pythonchallenge.com/pc/phonebook.php") as pb:
    print(pb.system.listMethods())
    print(pb.system.methodHelp('phone'))
    print(pb.phone("eval"))
    # 要用IE打开 http://www.pythonchallenge.com/pc/return/evil4.jpg
    # 得到提示 Bert is evil! go back!
    print(pb.phone("Bert"))

得到信息：555-ITALY
