Why is it showing Try again?

I don't understand my mistake regarding this laps and fuel_remaining.

racecar.py 
class RaceCar:
    laps = 0

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

You're very close. A return is meant to return the value of an expression and terminate execution of the current function/method.

So the only change you need to make is to NOT use any return statements in run_lap.

Also, pay close attention to part 3 of the challenge, it will require one more change to your code, but you got this far so I know you can handle it!

Good luck with Python, it is a fun journey!
