All functions without a return statement return None in Python. If you want to return another value, include a return statement.

In your case however, apply_raise() is a "procedure", logically speaking: it does something (apply a raise) but it does not need to return any value. You could perhaps execute the action, then print the employee's pay instead of the result of the function.
