Couldn't find the `RaceCar` class

This is giving the error that I mentioned in heading. I really couldn't figure out what is wrong with this code.

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

my_car = RaceCar(red, 5)
my_car.run_lap(3)

It looks like you just forgot to include the "self" parameter in "run_lap".

And for the challenge, you only need to define the class. You won't need to create an instance or call any methods on it.

Yes it worked. Thank you Steven.
