I think I followed the prompt exactly and I can't find my mistake. Please help
class RaceCar:
def __init__(self, color, fuel_remaining, laps = 0, **kwargs):
self.color = color
self.fuel_remaining = fuel_remaining
for key, value in kwargs.items():
setattr(self, key, value)
def run_lap(self, length):
return self.fuel_remaining - (length * 0.125)
self.laps += 1

- code after a "return" line will never be executed
- the "run_lap" only needs to update the internal variables, it doesn't need to return a value
- the new fuel amount is being calculated, but not stored
