- Visit the source page, and just see "zip" is useful
- http://www.pythonchallenge.com/pc/def/channel.zip -> get a zip file
- Unzip the file, you will know that it is just like challenge level 4. According the readme.txt, you should start from 90052
- Find "Collect the comment." in 46145.txt
- Modify the python code to collect the comments of the zipped files.

import re
import zipfile
filename = "channel/%s.txt"
filename_2 = "%s.txt"
var = 90052
content = ''
pattern = re.compile("Next nothing is ([0-9]+)")
re_result = []

zip_file = zipfile.ZipFile("channel.zip") 
comments = ''
while True:
 f = open(filename % str(var))
 content = f.read()
 f.close()
 re_result = re.findall(pattern, content)
 if len(re_result) == 0:
  print var, content
  break
 else:
  var = ''.join(re_result)
  comments = comments + zip_file.getinfo(filename_2 % str(var)).comment
  print comments

- The result shows:

- Firstly, I thought the answer would be "hockey", but indeed it is "oxygen".
