Question

The nutrition.py program (attached) creates a dictionary of food items (a mix of fruit and meat items) and displays their corresponding information. The dictionary has the food item code, and Food object as key and value respectively. Write the missing code, in the designated locations, in order for the program execution to yield the following output when the input number of food items is 5:

Enter number of food items:
5

Type: Fruit
Category: Apples & Pears
Code: 1012030
Name: Fruit_0
Sugar: 10g

Type: Meat
Category: Chicken
Code: 1012031
Name: Meat_1
Protein: 21%

Type: Fruit
Category: Berries
Code: 1012032
Name: Fruit_2
Sugar: 12g

Type: Meat
Category: Beef
Code: 1012033
Name: Meat_3
Protein: 23%

Type: Fruit
Category: Citrus
Code: 1012034
Name: Fruit_4
Sugar: 14g

Answer 1

Here is the completed python code for the above question.

Sometimes the code is not formatted properly, so I am attaching images of the code along with the output.

The line breaks can be modified for the output by using "\n" as per the requirement in the print statements.

import random

class Food:
    FRUIT_CATEGORIES = ["Apples & Pears","Citrus","Berries"]
    MEAT_CATEGORIES  = ["Beef","Chicken","Fish"]

    def __init__(self,code,name,category):
        self.code = code
        self.name = name
        self.category = category

    def info(self):
        print('\nType:',type(self).__name__)
        print('Category:',self.category)
        print('Code:',self.code)
        print('Name:',self.name)

class Fruit(Food):
    def __init__(self, sugar, code, name, category):
        self.sugar = sugar
        super(Fruit,self).__init__(code,name,category)

    def info(self):
        super(Fruit,self).info()
        print('Sugar:',str(self.sugar)+"g")  # Sugar content

class Meat(Food):
    def __init__(self, protein, code, name, category):
        self.protein = protein
        super(Meat,self).__init__(code,name,category)

    def info(self):
        super(Meat,self).info()
        print('Protein:',str(self.protein)+"%")  # Protein content

# Enter the number of food items
s = input("Enter number of food items:\n")
n = int(s)

foods = dict()
for i in range(0,n):
    code = "101203"+str(i)
    rd = i % 3
    if i % 2 == 0:
        food = Fruit(10+i%10,code,"Fruit_"+str(i),Food.FRUIT_CATEGORIES[rd])
    else:
        food = Meat(20+i%10,code,"Meat_"+str(i),Food.MEAT_CATEGORIES[rd])

    foods[code] = food

keys = list(foods.keys())
keys.sort()

for key in keys:
    foods[key].info()
