Personal Information Class: Design a class called Employee that holds the following data about an employee: name ID number Department Job Title Class. Store your class in a separate file called employee.py. Your class will have an initializer method that will be passed the information entered by the user as arguments. Write appropriate accessor and mutator methods for each data attribute. Write a __str__ method to print the contents of the class (see example of __str__ on p. 523). Main program: Your main program should create three instances of the class. Your program should get the information from the user and pass it as parameters to the initializer method. Using the __str__ method invoked by the print function, the program should display the personal information for the three individuals.
