Challenge Task 2 in classes

Question

what is wrong in the below code ?, Thanks in advance.
Question :
Vrroom!
OK, now let's add a method named runlap. It'll take a length argument. It should reduce the fuelremaining attribute by length multiplied by 0.125.
Oh, and add a laps attribute to the class, set to 0, and increment it each time the run_lap method is called.
Code:
class RaceCar:
    laps = 0
    def init(self, color, fuelremaining, **kwargs):
        self.color = color
        self.fuelremaining = fuelremaining
        for key, value in kwargs.items():
            setattr(self, key, value)
    def runlap(self,length):
        self.laps = self.laps +1
        return (self.fuel_remaining - length * 0.125
racecar.py
class RaceCar:
    laps = 0
    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        for key, value in kwargs.items():
            setattr(self, key, value)
    def run_lap(self,length):
        self.laps = self.laps +1
        return self.fuel_remaining - length * 0.125

It looks like you're returning a value that they expect you to be updating.
python
class RaceCar:
    laps = 0
    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        for key, value in kwargs.items():
            setattr(self, key, value)
    def run_lap(self,length):
        self.laps = self.laps +1 # Take a look at what you did here to update the number of laps done.
        return self.fuel_remaining - length * 0.125 # This should look similar to the above code.

You've got the right idea, so hopefully this will give you a nudge in the right direction. If you still feel stuck, let me know and we can walk through a solution. Nice work, and happy coding!
