TOPIC: Inheritance

In Python, modify the given code based on the given specifications below. Create another class, “Food.”

For the Food class, the specifications are:

The object will have the following attributes on initialization:

weight (weight of the food in kg)
energy_add (amount of energy it will add once consumed)
happiness_add (amount of happiness it will add once consumed)

Modify the Child and the Friends classes such that:

Instead of accepting a string (as food) in the eat method, the method should accept a Foodobject
Once a Child/Friendsobject eats a Food object:
- The added weight should be the Food object’s weight
- The added energy should be the Food object’s energy_add
- The added happiness should be the Food object’s happiness_add

The given code (can also be found on the picture):

class Child:

def __init__(self, child_number: int, name: str, weight: float):

self.child_number = child_number

self.name = name

self.weight = weight

def eat(self, food: str):

self.weight = self.weight + 0.50

def exercise(self, exercise: str):

self.weight = self.weight - 0.50

def weight_in_grams(self):

return self.weight * 1000

class Friends(Child):

energy = 50

happiness = 50

def eat(self, food: str):

self.energy = self.energy + 10

self.happiness = self.happiness + 10

return Child.eat(self, food) and self.energy and self.happiness

def exercise(self, food: str):

self.energy = self.energy - 10

self.happiness = self.happiness + 10

return Child.exercise(self, food) and self.energy and self.happiness

class Child:
def _init_(self, child_number: int, name: str, weight: float):
self.child_number = child_number
%3D
self.name = name
self.weight = weight
def eat(self, food: str):
self.weight = self.weight + 0.50
def exercise(self, exercise: str):
self.weight = self.weight - 0.50
def weight_in_grams(self):
return self.weight * 1000
class Friends(Child):
energy = 50
happiness = 50
%3D
def eat(self, food: str):
self.energy = self.energy + 10
self.happiness = self.happiness + 10
return Child.eat(self, food) and self.energy and self.happiness
%3D
def exercise(self, food: str):
self.energy = self.energy - 10
self.happiness = self.happiness + 10
return Child.exercise(self, food) and self.energy and self.happiness
