(Write code in Python)

Write a class named Employee that holds the following data about an employee in attributes: name, ID_number, department, and job title.

Create a UML diagram for Employee class.

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

Look up an employee in the dictionary

Add a new employee to the dictionary

Change an existing employees name, depart, and job title in the dictionary

Delete an employee from the dictionary

Quit the program

When program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.
