Bummer: Hmm, some attributes didn't get set correctly

object oriented python

racecar.py 
class RaceCar:
    def __init__(self, laps, color = 'blue', fuel_remaining = 20, **kwargs):
        self.color = color
        self.laps = laps
        self.fuel_remaining = fuel_remaining
        for k, v in kwargs.items():
            setattr(self, k, v)

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

red_car = RaceCar(10)

laps does not have to be a keyword / argument when creating an instance of the RaceCar. you can simply set the laps under the init to 0.

If you set the self.laps outside of the init then it becomes a class variable that will be changed whenever class.laps is changed. thus all following instances created after this will have a different laps attribute.

def __init__(self, color, fuel_remaining, **kwargs):
    self.laps = 0
