You will be better off in the long run if you try to solve these minor 
questions yourself.

Break the problem down:

First step: *split* the destAddress into 6 strings
Second step: convert the strings to *long* integer, remembering to use 
base 16 arithmetic
Third step: use the resulting 6-element list when creating "data".

Why do you think you need array.array('L', ....)? What are you going to 
do with "data" after filling it with the address?
