图片是一个饼干和一副小图，标题是：eat?   就没有其他的提示了

——————————————————————————————

百度了一下看看别人的思路：

1.The picture shows cookies, and there’s an inset with the sawhorse picture from level4 .

2.【首先通过cookies的提示，需要查看cookies信息，然后知道需要回到第四关，然后用busynothing 替代 nothing，重复第四关的遍历，不过这次需要收集的是每一个页面的cookies信息，然后利用bz2处理这些信息，然后再回到第13关打电话给mozart的老爹…用获得的信息修改新页面的cookies，最后得到谜底，】

————————————————————————————————————————————————

这实在是超出我的能力，，继续：

开始我百度的信息实在过于太少，后来找到了一个视频。推荐给大家：

# -*- coding: utf-8 -*-

import  urllib.request,urllib.parse
import  http.cookiejar
import  re,bz2

info=[]
#建立cookie管理,和授权代理程序
cookies=http.cookiejar.CookieJar()
auth_handler = urllib.request.HTTPBasicAuthHandler()
#添加密码到授权管理
auth_handler.add_password('inflate', 'www.pythonchallenge.com', 'huge', 'file')
#绑定cookies
cookie_handler=urllib.request.HTTPCookieProcessor(cookies)
#建立openerdirector对象
opener=urllib.request.build_opener(cookie_handler,auth_handler)

#打开链接
reqs=opener.open('http://www.pythonchallenge.com/pc/def/linkedlist.php')
reqs_data=reqs.info()
print(reqs_data)
print(list(cookies))

————————————————————————————————————————————————————————————————————————————
根据其中的信息：

you+should+have+followed+busynothing...

所以知道家该学第一关一样进行迭代。。

#定义下一页迭代函数
def next_page():
#使用列表保存每个网页的cookie中的value值
    cookieinfo=b''
    path='http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing='
    busynothong='12345'
    for i in range(400):
            f=opener.open(path+busynothong).read()
            text=f.decode('utf-8')
            m = re.search('and the next busynothing is ([0-9]+)', text)
            #如果匹配，取数字串，否则中断
            if m:
                busynothong = m.group(1)
            else:
                print('异常！')
                break
            print(text,busynothong)
            #取出cookievs的value的值
            cookieinfo+=(list(cookies)[0].value).encode('utf-8')
    return cookieinfo

——————————————————————————————————————————————————————————————————————————————

然后把得到列表进行解码解压缩，但是我的电脑不知道怎么回事。。使用unquote（）方法解码出来的是乱码，一直解决不了

所以引用的是别人的代码，我反正没试出来

cookie_bzd=bz2.decompress(urllib.unquote_plus(cookieinfo))  

——————————————————————————————————————————————————————

结果为：

is it the 26th already? call his father and inform him that "the flowers are on their way".
he’ll understand.

——————————————————————————————————————————————————————————————————

这是利用第13关莫扎特的那个phone（）方法，

import xmlrpc.client
server = xmlrpc.client.Server(r'http://www.pythonchallenge.com/pc/phonebook.php')
print (server.system.listMethods() )
print (server.system.methodHelp('phone')  )
print (server.phone('Leopold') )

————————————————————————————————————————————————————————————————

结果为：

'555-VIOLIN'

我们把13关的网址改为：http://www.pythonchallenge.com/pc/return/violin.html

得到的提示为：no! i mean yes! but ../stuff/violin.php.

然后我尝试一下新网页：http://www.pythonchallenge.com/pc/stuff/violin.php

标题为：it's me. what do you want?

那这是什么意思啊？？

————————————————————————————————————————————————————

看看别人的答案。原来是要根据上面的答案：【

is it the 26th already? call his father and inform him that "the flowers are on their way".
he’ll understand.

将其中

the flowers are on their way

存到cookie中

————————————————————————————————————————————————————————————————————

import urllib.request,urllib.parse

url='http://www.pythonchallenge.com/pc/stuff/violin.php'
req = urllib.request.Request(url,headers={'Cookie':'info=the flowers are on their way'})
rs=urllib.request.urlopen(req)
print(rs.read())

————————————————————————————————————————————————————————————

最终得到的答案为：

noh well, don\'t you dare to forget the balloons.
