what is wrong in the below code ?, Thanks in advance.
Question : 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.
Code: 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.laps = self.laps +1 return (self.fuel_remaining - length * 0.125
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.laps = self.laps +1
return self.fuel_remaining - length * 0.125

18,814 PointsIt looks like you're returning a value that they expect you to be updating.
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.laps = self.laps +1 # Take a look at what you did here to update the number of laps done.
return self.fuel_remaining - length * 0.125 # This should look similar to the above code.
You've got the right idea, so hopefully this will give you a nudge in the right direction. If you still feel stuck, let me know and we can walk through a solution. Nice work, and happy coding!
