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

after the laps argument, my code seems to be wrong, can someone tell me what is the error, please?

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

I improved the code, but still am. not able to pass the test:

class RaceCar:

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

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

def run_lap(length): #<-- you are forgeting the self infront of length
    self.length =. length #<-- length does not need a self. because it is a local variable
    return self.fuel_remaining - (self.length * 0.125) #<-- it does not need to be returned, it only need to be updated
    return laps + 1 #<-- same here it just needs to be updated
    #Also you can't have 2 returns back to back. Once it reaches to the first return it will return that thing and will break out of the method.

# Check this method, this is the correct way of doing it
def run_lap(self, length):
        self.fuel_remaining -= length * 0.125
        self.laps += 1
