i am trying to add a default lap variable in my constructor init. but whenever I put laps = 0, it shows error.

racecar.py 
class RaceCar:
    color = "blue"
    fuel_remaining = 50
    laps = 0


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