Introduction

In this lab we will implement a one-to-many relationship between a Owner and Pet.

Instructions

This is a test-driven lab. Run pipenv install to create your virtual environment and pipenv shell to enter the virtual environment. Then run pytest -x to run your tests. Use these instructions and pytest's error messages to complete your work in the lib/ folder.

Instructions:

Define a Pet and pass into the constructor the properties name and a pet_type.
Define an Owner class and pass into the constructor a name property.
In the Owner class write a method called add_pet(self, pet) that adds pets to a pets list for the owner.
In the Owner class write a method called remove_pet(self, pet_name) that takes a pets name and removes the pet from the Owners pets list.
In the Owner class write a method called sort_pets_by_name(self) returns a sorted list of pets by their names.
The attributes of Owner and Pet should be protected and have getters and setters.
