Here's what it says:
Oops, try again.
Make sure you pass the self keyword to the display_car() method.
But I did pass it. Or did I? What am I doing wrong?
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 %s %s with %s MPG" % (self.color, self.model, str(self.mpg)) my_car = Car("DeLorean", "silver", 88) print my_car.display_car("DeLorean", "silver", 88)
