Others have already told you how to do this. But I have 
a question: why do you care that it is a tuple, not a 
list? Is there something you need to do with it that 
can be done with tuples but not lists?

In other words, while it isn't *wrong* to convert the 
list to a tuple, perhaps it is *unnecessary*?
