Question

PetStore Class Write a class named PetStore with the following attributes and methods. Save this class as PetStore.py

Attributes __animals: a list used to store Animal objects.

Methods __init__: use this method to create an empty list for __animals.

add_animal: this method should receive an Animal object and append it to the __animals list.

#THIS IS EXTRA CREDIT delete_animal: this method should ask the user for a name for a animal and then remove them from the list.

show_animals: this method will print information about each of the Animal objects within __animals. If no Animals have been added to the list, it should print out a message saying that there are no Animals.

PetStoreManager Program Once you have written the Animal and PetStore classes, create another program called petstoremanager.py. This program will use Animal.py and PetSore.py as modules.

In petstoremanager.py, create a PetStore object and print a menu with three options(four with extra credit): Add Animal, Delete Animal, Show Animals, and Exit.

Add Animal: choosing this option should prompt the user to enter the type and name of an Animal. Use that input to create an Animal object and use the Store object’s add_animal method to store the animal.

Delete Animal: choosing this option should trigger the PetStore object’s delete_animal method.

Show Animals: choosing this option should trigger the PetStore object’s show_animals method.

Exit: this should exit the program. If exit is not selected, the program should loop and display the options again.
