why doesnt this work?

I don't get it maybe because the order? can anyone explain?

racecar.py 
class RaceCar:




    def __init__(self,laps=0,color,fuel_remaining,**kwargs):
        self.color=color
        self.fuel_remaining=fuel_remaining
        self.laps=laps

        for attr, values in kwargs.items():
            setattr(self,attr,values)

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

The challenge is expecting the first argument to be "color" but it has been changed here to "laps".

In fact, "laps" doesn't need to be an argument at all, it can always be initialzed to 0.

But the challenge asked me to put it as an argument :)

The instructions for task 1 specifically say, "In the __init__ for the class, take arguments for color and fuel_remaining. ".

Then for task 2, they say, "...and add a laps attribute to the class..." The only new argument mentioned is the length argument for the new method run_lap.
