Can someone please tell me where I am going wrong with my code? OOP Master Class challenge part 2

I got past the first part of the challenge, but then I got the error to add that laps = 0, which I did. Now it's saying "try again!" without saying where I am going wrong. Can someone please explain what is wrong with it? Thank you!

Here are the instructions: "OK, now let's add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining attribute by length multiplied by 0.125. Oh, and add a laps attribute to the class, set to 0, and increment it each time the run_lap method is called."

racecar.py 
class RaceCar:
    def __init__(self, color, fuel_remaining, laps, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0
        for key, value in kwargs.items():
            setattr(self, key, value)

    def run_lap(self, length):
        self.fuel_remaining -= length *0.125
        self.laps += 1

You're really close! But "laps" should not be a required argument to create an instance (it's always set to 0 internally).

I just got it to work! For the 2nd part of the challenge, I had to set laps to 0, but the 3rd part of the challenge said that we could remove it just like you said. Thank you for replying!
