a$)$ Create a class, Doctor, with the following data members and methods. Note all data

members and class variables should be private $(\_\_).$

Data Members:

$$ dname: stores the name of the Doctor.

$$ title: stores the title of the Doctor $($Professor$,$ Associate Professor,

Assistant Professor, Specialist$)$ Methods:

$\_\_$init$()\_\_$: initializes the name and type to values passed as parameters.

$$ Get and Set methods for dname and title.

$\_\_$eq$\_\_$ : attendee object are equal if their name and title are the

same.

$\_\_$lt$\_\_$ : an Doctor is less than another based on their alphabetic

titles, if the titles are the same it then compares according to

alphabetic name.

$$ repr$()\_\_$: returns a string representation of a Doctor object.

Format: $$Title $$ Doctor Name$$

b$)$ Create a class, Private, which is a subclass of Doctor. The subclass has the following data members and methods. Note all data members and class variables should be private $(\_\_).$

Data Members:

$$

Methods: $$

$$

patients: stores the integer number of patients seen by the Doctor. treatmentFee: stores the fee per patient for a treatment.

$\_\_$init$()\_\_$: initializes the dname and title by calling the super class init method. Initializes the number of patients and treatment fee to values passed as parameters.

calculate$\_$payment : calculates and returns the payment, which is the number of patients multiplied by the treatment fee.

repr$()\_\_$: returns a string representation of a Private object. Format: $$Title $$ Doctor Name Payment: payment

$$

c$)$ Create a class, State, which is a subclass of Doctor. The subclass has the following data members and methods. Note all data members and class variables should be private $(\_\_).$

Data Members:

$$ salary: stores the monthly salary of the State Doctor.

$$ baseBonus: the same for all State Doctors, defined as a static class

member, not inside the init method. Constant value $5000.$ Methods:

$\_\_$init$()\_\_$: initializes the dname and title by calling the super class init method. Initializes the salary to the value passed as parameters.

$$ calculate$\_$payment : calculates and returns the payment, according to the following: Professors receive their salary plus $125\%$ of the baseBonus, Associate Professors receive their salary plus $100\%$ of the baseBonus, AssistantProfessors and Specialists receive their salary plus $75\%$ of the baseBonus.

$$ repr$()\_\_$: returns a string representation of a State object. Format: $$Title $$ Doctor Name Payment: payment

$$

d$)$ Write an application, Lab$07.$py that does the following:

$$ Reads the data from the file doctor$\_$data.txt$.$ Using the data from the file, creates

Doctor objects $($State or Private$)$ and if the Doctor is not already in the list, adds

the Doctor to a list.

$$ Sorts the list of Doctors.

$$ Displays the sorted list of Doctors.
