Fair enough, although if you ask me the + 1 is just as magical as the + 7 (it's still the length of the string that you're searching for). Also, re-finding the opening ' still repeats information. The main thing I wanted to fix was that the second .index() call had the possibility of raising an unhandled ValueError. There are really two things we have to search for in the line, either of which could be missing, and catching them both with the same except: clause feels better to me than checking both of them for -1.
