What is incorrect with the run_lap method?

I'm unsure what is incorrect with the run_lap method I wrote. Is the self.fuel_remaining equation written incorrectly?

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

Melissa Benton two things wrong. You forgot to add self in front of laps. Also you are not setting fuel remaining. It should be -= instead of - . Hope this helps and keep at it!
