Race car class not working

Hello, what is wrong here? I am not sure if the run lap method needs to take self as anargument as well.Also, can I pass in self.fuel_remaining into the run lap method to do the calulation their?

racecar.py 
class RaceCar:
    def __init__(self,color, fuel_remaining, laps, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = laps
        self.laps = 0
        for key, value in kwargs.items():
              setattr(self, key, value)



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

Three issues stand out for me:

  • the instructions don't ask for "laps" to be an additional init argument
  • calling "run_lap" should reduce the fuel remaining by the formula (instead of replace it)
  • the addition assignment operator is "+=" (not "=+")

logic is wrong for the fuel_remaining, please check it once you are not reducing it. instead you are assigning the same value. also check the method signature for the run_lap method
