Employee Management System

$$ Learning Objective: Using Python Classes and Objects

Problem Description:

In this problem, you will develop an employee management system using Python. Here are the brief requirements of the program:

$1.$ Write a class named Employee, that holds information about each employee in attributes such as name, ID number, department, and job title.

$2.$ Once you have written the class, Draw the UML diagram, and write a program that creates three objects of employee class, with following information and displays their details.

Name ID Number Department Job Title

Susanna Myer $47899$ Accounting Vice President

Mark Joseph $39119$ Info Tech Programmer

Joyce Roberts $81774$ Manufacturing Engineer

$3.$ Create a program that stores Employee details in a dictionary. Use employee ID number as the key. The program should present a menu that lets the user perform the following actions:

a$.$ Look up an employee in the dictionary

b$.$ Add a new employee to the dictionary

c$.$ Change an existing employee$$s name, department, and job title in the dictionary.

d$.$ Delete an employee from the dictionary

e$.$ Quit the program

$4.$ Create a new class named ShiftEmployee, that is a subclass of Employee class. The shift employee has additional attributes in addition to name, ID number, Department and Job Title. The additional attributes are:

$-$ Shift number $($an integer, such as $1,2,$ or $3)$

$-$ Hourly pay rate

The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift $1$ and night shift is shift $2.$

$5.$ Write appropriate accessors and mutators for each class.

$6.$ Once you have written the classes, write a program that creates an object of ShiftEmployee class and prompts the user to enter data for each of the object$$s data attributes. Store the data in the object, then use the object$$s accessor and mutator methods to retrieve it and display it on the screen. Demonstrate the Shift Employee class by creating at least $2$ shift employee objects.
