Yes, my first attempt at responding did that, but I changed it because that
makes the assumption that string.ascii_letters is in a specific order (did
you know that lowercase came first and uppercase second without checking?)

Bzzt. Wrong answer. Look closely at the middle of the string.
I did have:
>>> upone = string.maketrans(string.ascii_letters,
'z'+string.ascii_lowercase[:-1] +
'Z' + string.ascii_uppercase[:-1])
but as I said, that makes too many assumptions for my liking about the
contents of those variables.
