First, think about how to do this without writing code.

alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
key =   "XPMGTDHLYONZBWEARKJUFSCIQV"

The example shows "python rocks" being turned into
AQULEWKEMNJ

Do you see from the two strings how that works?  If you can see that, write
a description of how you encode a message.  Bring that back with some code
that does the same and you will get help
