Object Oriented Python

Hey, guys!

One of the assignments in the Python course has me stuck... Does anyone have an idea of what could be wrong with my code?

The instructions for the assignment are:

"OK, now let's handle the racecar running laps. Add a laps attribute to the RaceCar class and set it to 0. Add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining attribute by the length argument multiplied by 0.125 (length * 0.125). Also, increment the laps attribute by 1 each time the run_lap method is called."

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

# You don't need this line
self.length = length

# You need self. here
laps += 1 # self.laps += 1

self.length = length is needed for the answer to be correct
