PYTHON ONLY Design a class named Employee. The class should keep the following information in fields: Employee name Employee number in the format XXX$-$L$,$ where each X is a digit within the range of $0-9,$ and the L is a letter within the range A$-$M$.$ Hire date $($using Date Class$)$ Write one or more constructors and the appropriate accessor and mutator methods for the class. Next, write a class named ProductionWorker that inherits from the Employee class. The ProductionWorker class should have fields to hold the following information: Shift $($an integer$)$ Hourly pay rate $($a double$)$ The workday is divided into two shifts: day and night. The shift field will be an integer value representing the shift that the employee works. The day shift is shift $1,$ and the night shift is shift $2.$ Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the classes by writing a demo program that uses a ProductionWorker object.

Part $2$: ShiftSuperisor Class. In a particular factory a shift supervisor is a salaried employee who supervises a shift. In addition to a salary, the shift supervisor earns a yearly bonus when his or her shift meets production goals. Design a ShiftSupervisor class that inherits from the Employee class you created in part $1.$ The ShiftSupervisor class should have a field that holds the annual salary, and a field that holds the annual production bonus that a shift supervisor earned. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a demo program that uses the ShiftSupervisor object.

Part $3$: TeamLeader class. In a particular factory, a team leader is an hourly paid production worker who leads a small team. In addition to hourly pay, team leaders earn a fixed monthly bonus. Team leader are required to attend a minimum number of hours of training per year. Design a TeamLeader class that inherit from the ProductionWorker class you design in part $1.$ The TeamLeader class should have fields for the monthly bonus amount, the required number of training hours, and the number of training hours that the team leader has attended. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a demo program that uses the TeamLeader object.
