Laps on the Track

Can someone please show what I'm doing wrong. Thanks

racecar.py
class RaceCar():

    def __init__(self, color, laps = 10, fuel_remaining, **kwargs ):
        self.fuel_remaining = fuel_remaining
        self.color = color
        self.laps = laps

        for key, value in kwargs.items():
            setattr(self, key, value)


    def run_lap(self, length):

        self.fuel_remaining = self.fuel_remaining - length *0.125
        self.laps += 1        
class RaceCar():
    def __init__(self, color, fuel_remaining, laps=0, **kwargs):
        self.fuel_remaining = fuel_remaining
        self.color = color
        self.laps = laps

        for key, value in kwargs.items():
            setattr(self, key, value)

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

The issue was that laps should come after the fuel_remaining, maybe it's the design of the test, but having the args in the wrong order confuses the test.

You are saying to RaceCar whore to give birth to car ,who has crossed 10 laps ,lolz obviously you know it .

class RaceCar:

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

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