[Tutor] Python Challenge - Riddle 2

[John Carmona]

OK I am stuck on this one. I see what I need to do (correct me if I am 
wrong). But I need to write a script that will replace each letter by 
another one (In this case a --> c etc.). I look at String, List and 
Dictionary. I thought I could use the text.replace option but I am not sure. 
Anybody to put me in the right track.

Also how can I add my work email address (but keeping this one) to have the 
mail forwarded to me, they have cut access to my hotmail at work and I am 
wasting too much time in waiting to go home to check my emails from 
Python.org.

Many thanks
JC
