whats wrong !!!

i think everything is correct what am i missing

racecar.py 
class RaceCar :


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

    self.laps=0
    def run_lap(self, length):

        self.fuel_remaining -= (length * .125)
        self.laps += 1

You're pretty close! But the class doesn't need a "laps" argument, and self.laps should just be set to 0 to begin with.

There's also a stray assignment of self.laps outside of any method you can remove.

After those fixes, you should pass the challenge.
