I set laps to 0 but its still telling me to do so, I'm probably missing something but what

It told me to make a attribute called laps and set it to 0 so I did but it's still telling me to do so what am I missing

racecar.py
class RaceCar():
    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)
        laps = 0
        def run_lap(self, length):
            self.fuel_remaining - (length * 0.125)
            laps += 1

Inside of init, all instance attributes should start with self, so laps should be self.laps. Then when you increment it you will need to use self.laps += 1 there too.
