Object Oriented Python: Master Class Task # 2--What am I missing?

I assume I'm following the instructions for creating a "run_lap" method for this RaceCar class code close enough, and have tried adding extra attributes and arguments to the rest of the code I first put down in Task#1, based on what I'm seeing in the instructions. But it keeps telling me "Bummer: Try again!" I'm not getting any more feedback then that as to what the issue is. What am I missing in the code block for the "run_lap" method? Is there anything else I'm missing? If anyone can explain, or just give me a hint, I'd appreciate it. Thank you.

Michael

racecar.py 
class RaceCar:
    color = "My Color"
    fuel_remaining = 10
    laps = 0

    def __init__(self, color, fuel_remaining=10, 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):
        length = int(length)
        fuel_remaining = self.fuel_remaining - (length * 0.125)
        return fuel_remaining and self.laps += 1

  1. In the method run_lap() you need to reduce the fuel_remaining attribute , it means you should reduce self.fuel_remaining self.fuel_remaining = self.fuel_remaining - (length * 0.125)
  2. method def run_lap() should not return anything, so increment self.laps in the method run_lap() body, not in the return statement

Thank you for your reply, Mr. Volha. I was overthinking the instructions at first, but the solution ended up being rather simple and understandable. I wonder whether the full code I made could be simpler still, and will probably be going back to it to practice on my own in the future. Thank you once again for your feedback. Take care.
