Implement class Worker that supports methods:

• __init__(): Constructor that takes as input the worker’s name (as a string) and the hourly pay rate (as a number)

• changeRate(): Takes the new pay rate as input and changes the worker’s pay rate to the new hourly rate

• pay(): Takes the number of hours worked as input and prints 'Not Implemented'

Next develop classes Hourly Worker and Salaried Worker as subclasses of Worker. Each overloads the inherited method pay() to compute the weekly pay for the worker. Hourly workers are paid the hourly rate for the actual hours worked; any overtime hours above 40 are paid double. Salaried workers are paid for 40 hours regardless of the number of hours worked. Because the number of hours is not relevant, the method pay() for salaried workers should also be callable without an input argument.
