The following code gets an error: Oops, try again. milton.full_time_wage(0) returned None instead of the correct value: 0
I don't understand why.
class Employee(object): """Models real-life employees!""" def __init__(self, employee_name): self.employee_name = employee_name def calculate_wage(self, hours): self.hours = hours return hours * 20.00 # Add your code below! class PartTimeEmployee(Employee): def calculate_wage(self, hours): return hours * 12 def full_time_wage(self, hours): super(PartTimeEmployee, self).calculate_wage(hours) milton = PartTimeEmployee("milton") print milton.full_time_wage(10)
