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:

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
