If you want Jordan's result, that's easy:

result["jordan"]

But there's no concept of "the last" entry in a dict. They don't have
an order. Do you mean "the entry with the greatest key"? That could be
written thus:

result[max(result)]

because max(result) is the string "jordan".

Does either of those make sense for what you're doing?
