Question

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

SOLUTION-
I have solve the problem in python code with comments and screenshot for easy understanding :)

CODE-

Animal.py

Python version : 3.6
Python program to create class Animal
'''
class Animal:
  
   # constructor to initialize the values of animal type, name and mood
   def __init__(self, animal_type , name):
       self.__animal_type = animal_type
       self.__name = name
      
       value = random.randint(1,3)
       if value == 1:
           self.__mood = "happy"
       elif value == 2:
           self.__mood = "hungry"
       else:
           self.__mood = "sleepy"
          
   # function to return the animal type
   def get_animal_type (self):
       return self.__animal_type
  
   # function to return the name   
   def get_name (self):
       return self.__name
  
   # function to rteurn the mood  
   def check_mood(self):
       return self.__mood
#end of class Animal  

#end of Animal.py

Code Screenshot:

'''
animalGenerator.py
Python version : 3.6
Python program to implement class Animal

from Animal from Animal

       name = input("What is the animal's name? ")
       animal = Animal(animal_type,name) # create an animal
       animalList.append(animal) # add the animal to the list
       choice = input('Would you like to add more animals (y/n)? ')
       if choice.lower() == 'n':
           break
   # display the animal information      
   if(len(animalList) == 0):
       print('Empty Animal list')
   else:
       print('Animal List:')
       for animal in animalList:
           print(animal.get_animal_type()+" the "+animal.get_name()+" is "+animal.check_mood())
#call the main function
main()          
#end of program
#end of animalGenerator.py
