This is what outputs to the code screen:
This is a silver DeLorean with 88 MPG.
It should work, at least it's returning the correct answer...
class Car(object): condition = "new" def __init__(self, model, color, mpg): self.model = model self.color = color self.mpg = mpg def display_car(self): return "This is a %s %s with %d MPG." % (self.color, self.model, self.mpg) my_car = Car("DeLorean", "silver", 88) print my_car.display_car()
