Hi Doug,
I'm not a Python guru, but shouldn't you be putting the output of
file.split('\n') into a list, and not back into a string (for clarity's
sake?).
Also, if you have two trailing newlines on the file, your final string
will be '', so you should be doing clean1.append(i[26:40]) in your for
loop, right?
Let me know if that helps...
