Example of using a namedtuple as an alternative to dictionaries to store 10 top foods

[shivan-s]

Here is an example of implementing a NameTuple from the typing module.

from typing import NamedTuple, Tuple

class Food(NamedTuple):
    """
    Food
    
    parameters
    name (str): name of the food
    protein (Tuple(float, str)): amount and unit e.g. 10 g
    carbohydrate (Tuple(float, str)): amount and unit e.g. 10 g
    fat (Tuple(float, str)): amount and unit e.g. 10 g
    
    Example
    egg = Food("egg", 
               (10, g), # protein 10 grams
               (10, g), # carbohydrate
               (10, g), # fat
              )
              
    """
    name: str
    protein: Tuple[float, str]
    carbohydrate: Tuple[float, str]
    fat: Tuple[float, str]
        
    def __repr__(self):
        return f"""
{self.name}
{'-' * len(self.name)}
{'Protein'.ljust(15)}{self.protein[0]} ({self.protein[1]})
{'Carbohydrate'.ljust(15)}{self.carbohydrate[0]} ({self.carbohydrate[1]})
{'Fat'.ljust(15)}{self.fat[0]} ({self.fat[1]})
                """

food = Food('test', (10, 'g'), (10, 'g'), (10, 'g'))
food

>>>
test
----
Protein        10 (g)
Carbohydrate   10 (g)
Fat            10 (g)                

food.protein
>>>
(10, g)

This is an alternative to a dictionary to store 10 common foods. Let me know what you think.
