BlockPy: FinalExam$-$P$4$

A Media is a dictionary with the following keys:

"name": The name of this media

"kind": Either "movie", "song", or "game"

"duration": The length of this media in minutes

Define the function longest$\_$kind that consumes a list of Media and produces a string value representing the kind that had the highest duration. If the list is empty, return the value None.

You are not required to document of unit test the function.
