Keep getting be sure to set laps to zero message?
class RaceCar:
def __init__ (self, color, fuel_remaining, **kwargs):
laps = 0
self.color = color
self.fuel_remaining = fuel_remaining
for key, value in kwargs.items():
setattr(self, key, value)
def run_lap(self, length):
self.length = length
self.fuel_remaining -= (self.length*0.125)
self.laps += 1

Treehouse TeacherInside of init, all instance attributes should start with self, so laps should be self.laps.

Treehouse TeacherBecause you're not passing in a value for laps. You include items in the () if you want to pass in a value for that attribute.
