The indentation here looks suspicious. It is a very bad idea to indent
some lines with tabs and others with spaces - use one method or the
other.

Also, you are not saving the stripped versions of the strings
anywhere.

BTW - the strip method doesn't change the object in place, so I don't
see the point of the 'fname = (file)' line. I certainly don't
understand the brackets. In fact, why not just...

  files = [i.strip() for i in files]

My best guess is that you expected the 'file' variable to reference
into the list, but this won't happen - its one of those things that
depends on whether the values are mutable or immutable, and with for
loops it's the type of the items within the list (ie the strings) that
is important. Strings are immutable.

Yes, this mutable/immutable thing is a pain :-(

Anyway, if you don't like list comprehensions, you'll need to loop
through the indices using something like...

  for i in range(len(files)) :
    files[i] = files[i].strip ()

Hope this helps.
