Thanks for your help. Now moving to the next section with another problem here is the code that is not working. So please help and I will really do appreciate it if you explained when exactly I should add the self key word.
class Car(object): condition = "new" def __init__(self, model, color, mpg): self.model = model self.color = color self.mpg = mpg def display_car(self,model,color,mpg): return "This is a [color] [model] with [mpg] MPG." my_car = Car("DeLorean", "silver", 88) print my_car.display_car(model,color,mpg)
