It would help if you were to explain your issue.

But I noticed a few things right off, when you subtract from the fuel_remaining the result isn't being stored. You probably want to use a subtraction assigment operator there ("-=").

Also, your run_lap method should have self as the first argument, which you would also use to prefix the names of the the instance variables ("self.fuel_remaining" and "self.laps").

Please state the issue :O def run_lap(length): fuel_remaining -= length * 0.125 <--assign it to the variable laps += 1

Try this, it will help . never write laps = laps +1 it is not good use or design.

```class RaceCar:

def __init__(self,color,fuel_remaining,laps = 0,**kwargs):
    self.color = color
    self.fuel_remaining = fuel_remaining
    self.laps= laps
    for k,v in kwargs.items():
        setattr(self,k,v)

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