Thank you very much!

With Anomalous Monk's help, I was able to run the script. It takes about 15.1 seconds on my computer--and that is checking for the similarities of one verse. But, wow! Tk made it like a GUI! I'd never used Tk before--so that was a new experience. Interesting. I might have to try experimenting more with that at some point when I have time. For now, I just need a simple text-based process, and, let's see, about five and half days to index the entire Bible at that level.

Now I just need to set up a loop and redirect the output to a file. That shouldn't be too hard, should it? (I managed to do the latter already. Perhaps if I can isolate the logic from the GUI it might make it more efficient.)
