Issue : add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining

Not sure why I'm still getting an error. Can someone help me? Thanks

racecar.py 
class RaceCar:

    def __init__(self, color, fuel_remaining, **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

Hi there, Stacy Lee ! To be honest, I have no idea why you're getting an error. Your code copy/pasted into the challenge passes all steps for me which makes me believe there might be some caching issue either client-side or server-side. I might suggest copying the code you have here and completely restart the challenge and paste it in. You might even have to shut down your browser and restart it or log in and out of Treehouse and try.

Hope you get this figured out! :sparkles:
