What are you talking about?  I don't understand what you mean by 
"ignores whitespace between dictionary elements."

It's also easier if the 2d list is pre-initialized to "-"s, for example, 
then he can just print it out directly, and it'll format correctly.  
With the dictionary he has to jump through some hoops, and by his 
original post we can infer that he's probably not completely comfortable 
with Python yet, so it'll probably be harder for him to understand how 
to do this.

I can provide example code showing how simple it'd be, but then it'd 
give away the answer.
