It's been so long since I've seen such a nonsensical assignment. 
However, I can point out a few things that might clarify it for you, as
you've presumably seen the entire assignment.

If you're trying to produce destination from part1, part2, and part3, I
don't know why you don't just use
   part1 + part3

If you're required somehow to use all three variables, then you can just
use
   part1 + part2[0:0] + part3

There's no need to have a "null value" within part2.
