help! why is this not correct?

why is this not correct?

racecar.py 
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 -= self.length*0.125
        return self.laps += 1

code:

class RaceCar:
        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) 
                self.laps = 0
        def run_lap(self,length):
            self.fuel_remaining = self.fuel_remaining -(length*0.125) 
            self.laps += 1

The "run_lap" method does not need an explicit "return", it only needs to update the attributes.

Also, when you do use "return", it immediately ends the method, so no code after it will ever be executed.

Hello Steven, I tried removing return. "it says make sure you set laps to 0". I changed it to laps == 0. now it says "try again". something is not right. the task is : " OK, now let's handle the racecar running laps. Add a laps attribute to the RaceCar class and set it to 0. Add a method named run_lap. It'll take a length argument. It should reduce the fuel_remaining attribute by the length argument multiplied by 0.125 (length * 0.125). Also, increment the laps attribute by 1 each time the run_lap method is called."

There should not be a "laps" argument. Just set "self.laps" to 0 internally in the init.

Stephen, can you look at my code and tell me what's wrong with it? class RaceCar: def init(self, color, fuel_remaining, **kwargs): self.color = color self.laps = 0 self.fuel_remaining = fuel_remaining for key, value in kwargs.items(): setattr(self, key, value)

 def run_lap(self, length):
    return fuel_remaining - (length*0.125)
    run_lap += 1

Thanks!

I am so STUPID!!! class RaceCar: 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) self.laps = 0

 def run_lap(self,length):
        self.fuel_remaining = self.fuel_remaining - (length*0.125) 
        self.laps += 1

class RaceCar: 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 = self.fuel_remaining  - (length*0.125)
    self.laps = length +=1

I am in tears...crying now because I've tried everything and nothing works....maybe I can skip this challenge and still get my badge?

Here's another try that "went wrong": class RaceCar: 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 = self.fuel_remaining - (length * 0.125)
    self.laps +=1
    print(run_lap)

If you're still having trouble, create a new, fresh question instead of posting "answers" to a previous one. :see_no_evil:
