5. class definition for GameEnemy
Next, we want to start making enemies for our upcoming video game, so we will define a class called GameEnemy.
Every GameEnemy will have a name, an x location, a y location, and a number of hit points (which must be a non-
negative integer ). The_init__ method for GameEnemy will take all of these parameters (in that order) and store them
on the object. GameEnemy also needs a method called healthbar, which will allow us to show that enemy's health bar in
the game. It returns the enemy's name followed by a number of asterisks to show how many hit points it has left. The
exact format is shown below.
Sample runs should look like:
>>> enemy = GameEnemy ("TODD", 100, 200, 5)
>>> enemy.healthbar()
TODD: ******
>>> enemy-%
ence
100
>>> enemy-y
200

Python program for this project:
Patient Charges
Write a class named Patient that has attributes for the following data:
First name, middle name, and last name
Address, city, state, and ZIP code
Phone number
Name and phone number of emergency contact
The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute.
Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data:
Name of the procedure
Date of the procedure
Name of the practitioner who performed the procedure
Charges for the procedure
The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute.
Next, write a program that creates an instance of the Patient class, initialized with sample data.
Then,…
2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.

An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0.
