Feed animals

• Read the guideline before start All animals love delicious food. Let's create a new class to feed them. Create class Animal which constructor takes three arguments:

• name - the animal name
• appetite - an integer that shows how much food points this animal need to eat to be full.
• is_hungry - boolean that shows if animal is ready to eat with True default value.

Animal should have two methods:

• print_name - should print name in the following format: Hello, my name is {name}
• feed - should print Eating {appetite} food points..., set is_hungry to False and return number of eaten food points if animal is hungry. Otherwise, it should return 0.

Example:

lion = Animal("Lion", 25)
lion.print_name()  # "Hello, I'm Lion"
food_points = lion.feed()  # "Eating 25 food points..."
print(food_points)  # 25
print(lion.is_hungry)  # False
print(lion.feed())  # 0

There is a well-known fact that all cats eat 3 food points at a time. Also, they can catch a mouse. Write Cat class which is a child of Animal. It should have a constructor with two arguments:

• name - the name of a cat
• is_hungry - with True default value

Note: you need call the super class constructor with appetite equal to 3.

Cat should have only one additional method catch_mouse which should print The hunt began!

Example:

cat = Cat("Cat")
cat.print_name()  # "Hello, I'm Cat"
cat.feed()  # "Eating 3 food points"

cat2 = Cat("Cat", False)
print(cat2.feed())  # 0
cat2.catch_mouse()  # "The hunt began!"

The last class you should implement is a Dog class. Its constructor should have two arguments:

• name - the name of a dog
• is_hungry - with True default value

All dogs should have appetite equal to 7.

Dog should have one additional method bring_slippers that should print The slippers delivered!

Example:

dog = Dog("Dog")
dog.print_name()  # "Hello, I'm Dog"
dog.feed()  # "Eating 7 food points"

dog2 = Dog("Dog", False)
print(dog2.feed())  # 0
dog2.bring_slippers()  # "The slippers delivered!"

Now, it's time to feed many animals at a time. Implement feed_animals function which takes a list of animals and should return a sum of food points that is needed to feed all hungry animals from this list.

Example:

cat = Cat("Cat", False)
lion = Animal("Lion", 25, True)
dog = Dog("Dog")
feed_animals([cat, lion, dog]) == 28
