It means that you're trying to access the attribute 'letters' on a
module that doesn't have that attribute.

You need to find what the value of 'string' is at that point in the
code. If I had to guess, I would say the person who wrote the above
line was expecting 'string' to be bound to the Python standard library
module 'string'; but that the code you have binds that name to some
other module.

If you have a file called string.py in the same directory as your
script, move/rename/delete it.
Otherwise run python from the command line with the -v option and find
where it's getting the interloper string module from.

interloper: my new word of the day. Thanks!

PS: Another way would be to run the script with python -i, and when it
halts, execute:

import string
print string.__file__

You were correct! I went back to my work machine and there it was. For
some
insane reason I had a py file string.py in the same directory as the
script
I was working on.
