""" Task: Exercise 3.2
    Rewrite your pay program using try and except so that your program handles
    non-numeric input gracefully by printing a message and exiting the program.
    The following shows two executions of the program:
    Enter Hours: 20
    Enter Rate: nine
    Error, please enter numeric input
    Enter Hours: forty
    Error, please enter numeric input
