This problem will allow you to demonstrate your understanding of Python classes and objects,

inheritance, and polymorphism by creating a simple Zoo Management System. You will add the

functionality of a menu and the ability to accept user input when adding, creating, and listing

animals in the Zoo.

Instructions:

The zoo will have several animals, and each animal will have a name, age, and species.

Moreover, each animal will have a method make$\_$sound$(),$ which should return a string

representing the sound it makes. Perform the following steps:

a$.$ Create a Zoo class. This class should be able to store multiple animals. It should

have methods to add$\_$animal and remove$\_$animal. Also, add a method

get$\_$animals that prints a list of all animals currently in the zoo, including their

name, age, and species.

b$.$ Create an Animal parent class. This class should have attributes for name, age,

and species. Include a make$\_$sound$()$ method that returns a string representing

the sound the animal makes.

c$.$ Create two or more child classes that inherit from Animal $($for example, Lion and

Elephant $-$ you get to choose the animal types$).$ These child classes should

override the make$\_$sound$()$ method to return a sound specific to the animal they

represent.

d$.$ Your program should be interactive. It should provide a menu to the user that

allows them to add an animal to the zoo, remove an animal from the zoo, or list

all animals in the zoo. The user should be able to keep using this menu until they

decide to quit the program.

e$.$ When adding an animal, your program should ask the user for the animal's

name, age, and type. It should then create an object of the appropriate type, and

add it to the zoo.

f$.$ Ensure that your program handles errors appropriately. For example, it should

not crash if the user tries to remove an animal that isn't in the zoo.

g$.$ Comment your code. Your comments should explain clearly what each part of the

code does.

h$.$ Include a main loop that is automatically called if the script is not imported by

another script as a module.

i$.$ Hint: You can use the input$()$ function to get input from the user, and a loop to

keep showing the menu until the user decides to quit. You may want to use a

dictionary to map from animal types entered by the user to your animal classes.

When your program runs, it should match the expected output below exactly. Go back

in and put in labels as needed.
