4. class definition for Friend For the next version of the friends database (coming soon!), we want to use classes rather than dictionaries. Define a Friend class , where each Friend object will store that friend's name, height and favorite foods. The class should have an _init_ method that takes in that friend's name and height. It should have an add_favorite_food method that takes a string and adds that string to a set of favorite foods, and a number_of_favorite_foods method that returns the number of favorite foods for that friend. Sample runs should look like: >>> friend1 = Friend("dweezil", 175) >>> friend1.add_favorite_food("borscht") >>> friend1.add_favorite_food("borscht") >» friend1.add_favorite_food("bagel") >>> friend1.add_favorite_food("banana") >>> friend1.number_of_favorite_foods() 3 >>> friend1.name 'dweezil' >>> friend1.height 175
