In the first example, sorted() returns a list, which is assigned to the
name tricky (Python doesn't have variables - names simply point to
objects in memory), and then the for loop iterates over tricky, which
points to a list. In the second example, the for loop iterates over the
list that sorted() returns. The only difference between the two is that
the list that sorted() returns is assigned to a name in the first example.
