Python Challenge #006 - channel

The zip is a clue. The file can be opened with the zipfiles library.

>>> import re
>>> import sys
>>> import zipfile
>>> n = '90052'
>>> history = []
>>> f = zipfile.ZipFile("channel.zip")
>>> print(f.read(n + '.txt'))
b'Next nothing is 94191'
>>> print(f.getinfo(n + '.txt').comment)
b'*'

This function follows the nothings through the zipped files.

>>> def next_zip(n):
...   history.append(n)
...   text = f.read(n + '.txt').decode()
...   m = re.search('\d+', text)
...   if m is None: return m
...   n = m.group()
...   return n
...

Now collate the file comments in the zip archive in the order of the nothings.

>>> while n: n = next_zip(n)
... 
>>> print(''.join(f.getinfo(n + '.txt').comment.decode() for n in history))
