the RaceCar

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.

class RaceCar: laps = 0 

def __init__(self,color,fuel_remaining,**kwargs):
    self.color=color
    self.fuel_remaining = fuel_remaining

    for key, value in kwargs.items():
        setattr(self, key, value)

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