Doh. Never mind. _I'm_ the one who introduced that regression. :( Sorry!
Here's a corrected definition for rot1():

Thank you all for the help. I really appreciated the suggestions. Some of
the things you pointed out, I originally used, but started changing thing
when it wasn't working. I got it to work, but if you could let me know if
there is anything I should do to make this code more pythonesque that would

What can be said after this detailed lesson...Bravo!

The use of index() here to find the target place where the translation
is going to occur is very fragile.
Consider: we conceptually already should know where in the list we

the list. We know that we're looking first at ls[0], tra
