@kalt: look at the characters used to draw HOCKEY. O for H, X for O, etc.

where’s the word “oxygen” coming from?

Nope. 2.6 works just fine. But your zipfile is broken.

taher@borg:~/src/python_challenge$ unzip -l channel.zip
This should report 910 files in the compressed file.

I get:


Traceback (most recent call last):
  File "./channel.py", line 13, in 
    content = file.read(name + ".txt")
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/zipfile.py", line 836, in read
    return self.open(name, "r", pwd).read()
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/zipfile.py", line 859, in open
    zinfo = self.getinfo(name)
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/zipfile.py", line 826, in getinfo
    'There is no item named %r in the archive' % name)
KeyError: "There is no item named '90052.txt' in the archive"

when i run the script. Could it have something to do with the version of python I'm using?

Ugh
‘zip’ was misleading as it is a built in Python function, the hint should have read ‘.zip’
The comment information was lost when I automatically extracted the zip file – rendering hint2 completely misleading -> the answer isn’t inside the zip, it’s in the zip metadata.
Ugh

And what about the pairs? There were no pairs in the entire riddle. The 94191.txt is not part of the series. Why is that? It misleads me completely. I tried to combine the 2 series with the zip function and do various stuffs with the pairs, but it leads me nowhere.
(Btw, I had no idea about the comment field associated to each zip entry.)

ah ok. i never thought that these files have a comment field on them. thanks.

Those would be the comments for every single file zipped in the compressed archive. Try “unzip -l channel.zip | less” if it’s still unclear. :)
I don’t do Windows, so I’m not really sure how you could view the comments from there.

Ugh, I still don’t understand how you get from “Collect the comments” to hockey.html
