I don't know How to fit my code..

Is there something wrong in my 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(self,length):
        self.fuel_remaining -= length*0.125
        laps += 1

Just to nudge you in the right direction; you're not quite incrementing the laps class attribute correctly, but you're very close! Check back in the videos, or do a quick Google search on how to change class attributes in Python.

I think it's better to nudge you rather than directly tell you the answer when you're so close. Once you find out what's wrong you won't forget it again!

Thx that helped, classes are so specific about the self keyword. Does the self keyword make a variable a local variable Jon?

Self is just a reference to the object. Going back to the code in the original question, if you were to create two RaceCar objects; x and y and then call run_lap on x, then self will only reference RaceCar x and not y.

Hope that makes sense!

Makes sense. (I never asked this question btw)

Ah Sorry! I thought you were the OP :)

I've edited my answer to be a bit more general; glad I could help!
