Implementing Classes in Python: People, Food, and Activities
How to implement three classes in Python to represent people, food items, and a collection of ingredients?
The code you have provided defines three classes with the following attributes and methods:
- People class: Attributes: name, age, isAsleep, canCook, friends Methods: wakeUp, invite, __str__, __lt__
- Food class: Attributes: name, ingredients, prepTime Methods: __str__
- Activities class: Attributes: ingredientsDict Methods: cook, kidsTable, buyIngredients
Explanation:
The People class represents a person. The age attribute stores the person's age, the isAsleep attribute stores whether or not the person is asleep, the canCook attribute stores whether or not the person can cook, and the friends attribute stores a list of the person's friends. The wakeUp method wakes up the person if they are asleep, the invite method adds a person to the friends list, the __str__ method returns a string representation of the person, and the __lt__ method compares two people based on their ages.
The Food class represents a food item. The name attribute stores the food item's name, the ingredients attribute stores a list of tuples where the first element is the name of the ingredient and the second element is the number of servings required, and the prepTime attribute stores the time it takes to prepare the food item. The __str__ method returns a string representation of the food item.
The Activities class represents a collection of ingredients. The ingredientsDict attribute stores a dictionary where the keys are the names of the ingredients and the values are the current quantities of the ingredients. The cook method cooks a food item if there are enough ingredients, the kidsTable method returns a list of the four youngest people in a list of people, and the buyIngredients method adds an ingredient to the ingredientsDict if it is not already there, or updates the quantity of an existing ingredient.
