pythonchallenge 解谜 Level 6

第六关地址

和前几关一样，首先看网页源码吧。反正不看也没办法。。。

10 thought it would be the right point to offer you to donate to the
11 Python Challenge project. Any amount will be greatly appreciated.

有用的信息 zip。翻译是。　　以下与谜题本身无关。。。

所以有用的只有一个zip。一开始以为zip是一个网页，后来发现是把

http://www.pythonchallenge.com/pc/def/channel.html

变换成

http://www.pythonchallenge.com/pc/def/channel.zip

得到一个zip压缩文件。

使用python代码解压。（压缩包解压也可以）

 1 #-*- coding:utf-8 -*-
 2 #代码版本均为python 3.5.1
 3 #Level 6
 4 
 5 import zipfile
 6 import os
 7 import glob
 8  
 9 file = zipfile.ZipFile("channel.zip", "r")
10  
11 print ('''列出文件''')
12 for name in file.namelist():
13     print(name)
14  
15 print ('''列出文件信息''')
16 for info in file.infolist():
17     print (info.filename,"文件名")
18     print (info.date_time,"修改时间")
19     print (info.file_size,"大小")
20     print (info.compress_type,"压缩级别")
21     print (info.compress_size ,"压缩数据大小")
22     print (info.file_size,"未压缩文件大小")
23  
24 for i in range(1, 10):
25     print ("")
26  
27 print ('''解压操作 unzip''')
28 for name in file.namelist(): 
29     file.extract(name,os.getcwd()+"/zipfile_module") #解压到当前目录
30  
31 #关闭压缩文件句柄
32 file.close

和之前的一关有点相似。跑了一遍代码。发现提示说答案在压缩文件注释中。

最终代码

#-*- coding:utf-8 -*-
#代码版本均为python 3.5.1
#Level 6

import zipfile
import os
import glob
import re

file = zipfile.ZipFile("channel.zip", "r")
 

p = 90052

for name in file.namelist(): 
    line = str(file.read("%s.txt" % p))
    m = re.search('Next nothing is ([0-9]+)', line)
    print (file.getinfo("%s.txt" % p).comment.decode("utf-8"), end=" ")
    p = m.group(1)
