can anyone suggest what I did wrong in this code?

for the task 3 of 3, I do think I put laps inside the init, but still not right, can you help?

racecar.py
class RaceCar:
    def __init__(self, color, fuel_remaining, laps, **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(self, length):
        self.fuel_remaining -= length * 0.125
        self.laps += 1

Hi there,

You're close. The question says about laps, it doesn't have to be a keyword argument, though.

So, just set laps to zero inside __init__, rather than pass it in as an argument:

class RaceCar:
    #laps = 0
    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

I hope that helps,

Steve.
