6. 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 ● The Patient class's init__ method should accept an argument for each attribute. The Name and phone number of emergency contact 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 107 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.

Personal Information Class: Design a class called Employee that holds the following data about an employee: name ID number Department Job Title Class. Store your class in a separate file called employee.py. Your class will have an initializer method that will be passed the information entered by the user as arguments. Write appropriate accessor and mutator methods for each data attribute. Write a __str__ method to print the contents of the class (see example of __str__ on p. 523). Main program: Your main program should create three instances of the class. Your program should get the information from the user and pass it as parameters to the initializer method. Using the __str__ method invoked by the print function, the program should display the personal information for the three individuals.
