Chapter 10, Problem 7PE

Employee Management System

This exercise assumes you have created the Employee class for Programming Exercise 4. 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 employee's name, department, and job title in the dictionary

■ Delete an employee from the dictionary

■ Quit the program

When the 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.
