Question 2 (18 marks) Demonstrate your understanding of how class hierarchy and association are used to organize information, and then construct the class hierarchy and association according to specification. The class diagram in Figure Q2 shows the specifications of the Deli class and its subclasses: HotDeli and ColdDeli. STANDARD EXPIRY: 2 deliCode: str _name: str _price: float _fat: float _carbohydrates: float _protein: float expiryHours(self): float _init_(self, deliCode: str, name: str, price: float, Dell (abstract) delicode(self): str fat: float,carbohydrates: float, protein: float) name(self): str price(self): float fat(self): float ColdDeli _storageTemperature: float calories(self): float expiryHours(self): float (abstract) _str_(self): str _init__(self, deliCode: str, name: str, price: float, fat:float, carbohydrates: float, protein: float, storageTemperature: float) HotDeli _COOKING STYLE_EXPIRY: {"Steaming": 1.

The Deli class represents a food item that the ERP is offering. ONE class variable that defines the standard expiry hours as 2. SIX instance variables: o _deliCode (str): unique code for this deli item, e.g., "H001". o name (str): name of the deli, e.g., "Croissant". o_price (float): the price for this deli. _fat (float): per serving of fat in grams. o carbohydrates (float): per serving of carbohydrates in grams. (c) . Define getter method for calories. Use the property decorator. To compute calories, use the following formula: o Fat provides 9 calories per gram while carbohydrates and protein each provide 4 calories per gram One abstract method, expiryHours which returns the standard expiry hours. . o protein (float): per serving of protein in grams. Constructor initialises these 6 instance variables using the given parameters. Getter methods for these instance variables: _deliCode, _name, price and _fat. Use the property decorator. The _str___ method returns a string representation of a Deli object, with selected attributes in the following order - deliCode, name, price, fat, and calories, in the suggest format below: cee1 - Smoked Duck Salad H001 Croissant Price: $4.00 Fat: 12.5 Price: $2.50 Fat: 15.0 Write the Python class definitions for the ColdDeli and HotDeli The ColdDeli class is a subclass of Deli, and it has One additional instance variable, storage Temperature (float) that will help determine how long this cold food item can last. (d) Write Python statements to create the appropriate Deli objects using the information below: Code Name ceel Smoked Duck Salad Heel Croissant Price Fat Carbohydrates Protein $3.00 12.5 $2.00 7.5 Print the details of the Deli objects created. 13.4 15 Storage Temperature 16c Cooking style Baking (2 marks) Question 2 (18 marks) Demonstrate your understanding of how class hierarchy and association are used to organize information, and then construct the class hierarchy and association according to specification.
