Created on Feb. 24, 2022 by Driikolu

Implement a Dish and a Menu classes like so:

• Dish have a name, preparation_time, and a dish_type attribute , given in this order at initialization time.

• Dish's dish_type attribute value can be :

  • starter
  • dish
  • dessert

• Menu have a name attribute, given at initialization time.

• Menu have an add_dish(dish) method.
• When you compare 2 Dish items with the operators >, <, ==, <=, >=, it must compare its preparation_time.
• Menu have a get_starters() method giving all the Dish with "starter" dish_type
• Menu have a get_dishes() method giving all the Dish with "dish" dish_type

• Menu have a get_desserts() method giving all the Dish with "dessert" dish_type

• Menu have a get_minimum_preparation_time() method giving the sum of :

  • the lowest preparation_time from Dish with "starter" dish_type on the Menu (0 if there is no starter)
  • the lowest preparation_time from Dish with "dish" dish_type on the Menu (0 if there is no dish)
  • the lowest preparation_time from Dish with "dessert" dish_type on the Menu (0 if there is no dessert)

• Menu have a get_maximum_preparation_time() method giving the sum of :

  • the highest preparation_time from Dish with "starter" dish_type on the Menu (0 if there is no starter)
  • the highest preparation_time from Dish with "dish" dish_type on the Menu (0 if there is no dish)
  • the highest preparation_time from Dish with "dessert" dish_type on the Menu (0 if there is no dessert)

• When you add 2 Menu items with the + operator, it will return a third Menu containing the dishes (starters, dishes, desserts) of the 2 Menu and with name being the 2 Menu name separated by " & ".

eg :

>>> menu_1 = Menu("One")
>>> menu_2 = Menu("Two")
>>> menu_3 = menu_1 + menu_2
>>> print(menu_3.name)
One & Two

• When you print a Menu item it must :

  • Print all the Dish's name 1 per line sorted by dish_type (starter, dish, dessert) and preparation_time (lowest to highest)
  • Separate every dish_type by an empty line
  • Adding the dish_type all in uppercase before all the Dish with the given dish_type

Here is what it should look like :

>>> print(my_menu)
STARTER
eggs & mayonaise
salad

DISH
burger
pizza
coq au vin

DESSERT
chocolate cookie
waffle
