Not sure what to do here

I thought I addressed every aspect of the task but I guess I haven't. Not sure what else to do

racecar.py 
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)
            laps += 1

You're close, but you have a few issues:

  • the run_lap method is indented too far and appears to be inside the __init__ method
  • to reduce the fuel, you need a subtraction assignment ("-=") instead of just a subtraction operator
  • you forgot to prefix laps with "self." when incrementing it
