N00b question. But here is the code:

In the first example, the first for-loop is run and then the list is assigned
to the tricky variable. But, what
happens in the second example? Does the loop after "in" get run only once or
multiple number of times?
Just once. The sorted fn is called just once, and the resulting list is
iterated through. In your first case, the list is bound to (assigned
to) a name so it is accessible afterwards. In the second case, it is
available for garbage collection immediately after the loop finishes.
