Level 1 - Pythonic way additional hint

I'm relatively new to Python and am trying to do this in a python specific manner. I can see building a translation table and using the translate function, but this strikes me as brute force (and tedious). Can anyone give me another hint (or three) that will get me going in the right direction?

Thanks.

OK - just found out that the command I was expecting to build the translation function doesn't have to be as complicated as the rot-13 spec seems to make it. I found the answer and feel just a little silly now, but more informed than I was.
