Problem

I don't know what is wrong with this piece of code ?

racecar.py 
class RaceCar:
    color = ""
    laps = 0
    fuel_remaining = 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):
        fuel_remaining -= (length*0.125)
        laps += 1

Hi ! In Python you don't declare attributes outside the init method (actually you can but those attributes are then shared by every instances of the class), you should then do it like this :

class RaceCar:
    def __init__(self , color , fuel_remaining , **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0
        for key , value in kwargs.items():
            setattr(self , key , value)

    def run_lap(self , length):
        self.fuel_remaining -= (length*0.125)
        self.laps += 1
