Challenge: Animal Class
Question Description
Challenge: Animal Class
Description: Create a class in Python 3 named Animal
that has specified attributes and methods.
Purpose: The purpose of this challenge is to provide experience creating a class and working with OO concepts in Python 3.
Requirements:
Write a class in Python 3 named Animal
that has the following attributes and methods and is saved in the file Animal.py.
Attributes
__animal_type
is a hidden attribute used to indicate the animal’s type. For example: gecko, walrus, tiger, etc.
__name
is a hidden attribute used to indicate the animal’s name.
__mood
is a hidden attribute used to indicate the animal’s mood. For example: happy, hungry, or sleepy.
Methods
__init__
is to define the three attributes above and assign their default values.
The value of __mood
is to be set randomly. Generate a random number between 1 and 3. Then:
If the number is 1, the __mood
attribute is to be set to a value of happy.
If the number is 2, the __mood
attribute is to be set to a value of hungry.
If the number is 3, the __mood
attribute is to be set to a value of sleepy.
get_animal_type
should return the value of the __animal_type
field.
get_name
should return the value of the __name
field.
check_mood
should return the value of the __mood
field.
Animal Generator Program
Once you have created the Animal
class, create another Python file called animalGenerator.py. This program is to use Animal.py as a module.
In animalGenerator.py, prompt the user to enter the name and type of an animal. Create a new Animal
object instance to store this data. Then, ask the user if they would like to repeat the process. They should be able to create as many Animal
object instances as they would like.
After the user is done creating animals, the program is to use the object’s accessor methods (get_animal_type
, get_name
, and check_mood
) to retrieve the name, type, and mood of each animal. This information is to be formatted and displayed as shown in the sample program output below.
Welcome to the animal generator!
This program creates Animal objects.
What type of animal would you like to create? Gecko
What is the animal’s name? Gordon
Would you like to add more animals (y/n)? y
What type of animal would you like to create? Walrus
What is the animal’s name? Wally
Would you like to add more animals (y/n)? y
What type of animal would you like to create? Tiger
What is the animal’s name? Truman
Would you like to add more animals (y/n)? n
Animal List:
Gordon the Gecko is hungry
Wally the Walrus is sleepy
Truman the Tiger is hungry
Testing
Run the program you write and verify that the information entered matches the information displayed and that the input prompts and output utilize the format specification provided.
