Part B: Inheritance $(10$ Pts$)$

Instructions: $($pets$.$py$)$

In this part, you will write $2$ classes $($Dog and Panda$)$ that inherit all the functionalities from the Animal class and add some more.

Task $1$: Dog Class

It represents a dog entity with specific attributes and behavior. It is a subclass of class Animal that should include the following additional attributes and methods:

Attributes:

$-$In addition to the attributes inherited from the Animal class $($i$.$e$.,$x$,$ y$,$ id$,$ and species$),$ the Class should have the following attributes:

name: The dog$$s name. Default is "Dogzilla".

gender: The dog$$s gender. Default is "Female".

Methods:

$\_\_$init$\_\_()$ method: Accepts six arguments: self, name $($default "Dogzilla"$),$ gender $($default "Female"$),$ x $($default $0),$ y $($default $0),$ id $($default $100)$ in this order. It uses the constructor for class Animal to store species $("$Dog$"),$ x$,$ y$,$ andid as data attributes. Hint: check out how MassParticle calls the Particle $\_\_$init$\_\_$ in Code Listing $12\mathrm{.}11$

# Example usage:

animal $=$ Dog$("$Dogzilla$",$ "Female", $0,0,100)$

print$($animal$)$ # Animal Dog $($ID: $100)$ is at $(0,0)$

about$()$ method: Accepts one argument: self. It Returns a string introducing the dog, including its name and position. Additionally, it identifies the dog as a $$race watcher.$$

# Example usage:

animal $=$ Dog$()$

animal.about$()$

$\text{'}\text{'}\text{'}$

Hi my name is Dogzilla.

Animal Dog $($ID: $100)$ is at $(0,0).$

I$\text{'}$m your female dog race watcher.

$\text{'}\text{'}\text{'}$

Task $2$: Panda Class

representing a panda entity where you should be able to decide on the name$/$gender of your Panda. You can also interact with it by feeding your Panda, playing with your Panda, and talking to your Panda. It is a subclass of class Animal that should include the following additional attributes and methods:

Attributes:

$-$In addition to the attributes inherited from the Animal class $($i$.$e$.,$x$,$ y$,$ id$,$ and species$),$ the Class should have the following attributes:

name: The panda$$s name.

gender: The panda$$s gender.

fur$\_$color: The panda$$s fur color.

As well as some other attributes that are related to physical$/$mental health status:

hunger

thirst

loneliness

Methods:

$\_\_$init$\_\_()$ method: Accepts seven arguments: x $($default $0),$ y $($default $0),$ id $($default $0),$ name $($default "Fluffy"$),$ gender $($default "Unknown"$),$ and fur$\_$color $($default "Red"$).$

It uses the constructor for class Animal to store species $("$Panda$"),$ x$,$ y$,$ andid as data attributes.

When a Panda object is created, his$/$her initial status have a hunger and thirst level of $0.$ Their loneliness is at $10.$

Once all attributes are initialized, a message is printed from the animal$$s TALKS dictionary with a $$newborn$$ message $($TALKS$[$newborn$]).$

# Example usage:

animal $=$ Panda$(0,0,10,$ "Fluffy", "male", "Red"$)$

# Hi master, my name is Fluffy.

print$($animal$)$

# Animal Panda $($ID: $10)$ is at $(0,0)"$

status$()$ method: prints a string representation of the Panda$$s status.

# Example usage:

animal $=$ Panda$(0,0,10,$ "Fluffy", "male", "Red"$)$

animal.status$()$

$\text{'}\text{'}\text{'}$

Panda Fluffy $($ID: $10,$ Gender: male, Fur Color: "Red"$)$

Position: $(0,0)$

Hunger: $0,$ Thirst: $0,$ Loneliness: $10$

$\text{'}\text{'}\text{'}$

reply$\_$to$\_$master$()$ method: accepts as argument event. It prints a reply to the master based on the Panda$$s mood and status $,$ such as hunger, thirst, and loneliness.

event is a key that determines which specific message from the animal$$s TALKS dictionary to use for its initial reply. It first prints the animal$$s name followed by the message tied to the given event.

Then, it evaluates the animal$$s attributes:

Hunger $($hunger$)$ and Thirst $($thirst$)$: If both exceeds or equal $7,$ the animal replies with a $$tired$$ message $($TALKS$[$tired$]).$

Hunger $($hunger$)$: If greater than or equal to $5$ the animal replies with a $$hunger$$ messages $($TALKS$[$hunger$]).$

Thirst $($thirst$)$: If greater than or equal to $5,$ the animal replies with a $$thirsty$$ messages $($TALKS$[$thirsty$]).$

Loneliness $($loneliness$)$: If greater than or equal to $7,$ the animal replies with a $$loneliness$$ message $($TALKS$[$loneliness$]).$

If none of the above conditions are met, the animal replies with a $$default$$ message $($TALKS$[$default$]).$

# Example usage:

animal $=$ Panda$(0,0,10,$ "Fluffy", "male", "Red"$)$

animal.reply$\_$to$\_$master$(\text{'}$play$\text{'})$

$\text{'}\text{'}\text{'}$

Fluffy: Happy to have your company ~

Fluffy: Could you stay with me for a little while $?$

$\text{'}\text{'}\text{'}$

animal.hunger $=10$

animal.reply$\_$to$\_$master$(\text{'}$feed$\text{'})$

$\text{'}\text{'}\text{'}$

Fluffy: Yummy $!$

Fluffy: I$\text{'}$m too hungry or thirsty to talk right now...

$\text{'}\text{'}\text{'}$

play$()$ method: This method does not take any parameter. It will update the loneliness attribute. It Reduces loneliness by $3$ but increases hunger and thirst slightly by $3.$ It ensures that loneliness does not go below $0$ and that hunger and thirst does not go above $10.$

It will then call the reply$\_$to$\_$master$()$ method with the 'play' event.
