The instructions are: "Vrroom! OK, now let's add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining 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." I have looked through the other questions about this challenge and made several of their suggested changes, but I still get bummered. I would really appreciate any help. Thanks in advance. :)
class RaceCar:
def __init__(self, laps = 0, color, fuel_remaining, **kwargs):
self.color = color
self.fuel_remaining = fuel_remaining
self.laps = laps
for key, value in kwargs.items():
setattr(self, key, value)
def run_lap(self, length):
self.fuel_remaining -= length * 0.125
self.laps += 1
