Not sure what is wrong with my code

OK, now let's handle the racecar running laps. Add a laps attribute to the RaceCar class and set it to 0. Add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining attribute by the length argument multiplied by 0.125 (length * 0.125). Also, increment the laps attribute by 1 each time the run_lap method is called.

Thank you

racecar.py
class RaceCar: 
    def __init__(self,color,laps = 0,fuel_remaining,**kwargs):
        self.color = color
        self.laps = laps
        self.fuel_remaining = fuel_remaining

        for key,value in kwargs.items():
            setattr(self,key,value) 
    def run_lap(self,length):
        self.fuel_remaining = self.fuel_remaining - (length * 0.125)
        self.laps = self.laps + 1

You are SO close! In the __init__ method definition the parameters with default values must come after regular parameters. So moving laps=0 after fuel_remaining will fix the code.

Post back if you need more help. Good luck!!!
