If the number is 1, the
__mood
field should be set to a value of “happy”.

Zoo Class
Zoo Class
Write a class named Zoo
with the
following attributes and methods. Save this class
as
Zoo.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.
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.
Zookeeper
Program
Once you have wri
tten the Animal and Zoo classes, create another program called
zookeeper.py
. This program will use
Animal.py
and
Zoo.py
as modules.
In zookeeper.py, create a Zoo object and print a menu with three options: Add
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 creat
e an Animal object and use the
Zoo object’s
add_animal
method to store the animal.
Show Animals:
choosing this option should trigger the Zoo 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.
