I want to know what's wrong with my code

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

Looks like you have a pretty good start on this... let's build on that.

1 - issues with indentation need to be addressed the run_lap() method needs to be outdented by 4

2 -The laps variable needs to referenced to the self object

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 = self.fuel_remaining - (0.125*self.length)
        self.laps += 1 # fix here

Also note, on part 3 of the challenge, they will ask you to change the laps from a class variable to an instance variable. I will leave that to you to figure out.

Best of luck with Python!
