hello i am still stuck on this task in OOP the video doesn't help me i need tips

should laps = 0 be self.laps = 0 what else is wrong with my code?

class RaceCar:
    laps = 0 
    def __init__(self, color=None , fuel_remaining=None, **kwargs):

        self.color = color
        self.fuel_remaining = fuel_remaining

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



    def run_lap(self, length):

        self.fuel_remaining-= * 0.125

Hi there,

Since you have run_lap, I'm guessing you're on the second step. That means your _init_ passed, so let's look at what we need to do to run_lap:

  • the fuel_remaining should be reduced by the length value multiplied by 0.125 - so, we need to add "length" in there.
  • we don't need the class name in the next line - just self.laps
  • we need to take the space out between the + and the =

That leaves us with something like this:

class RaceCar:
    laps = 0 
    def __init__(self, color=None , fuel_remaining=None, **kwargs):

        self.color = color
        self.fuel_remaining = fuel_remaining

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



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

Good luck!
