code does not work, i cannot find th solution, though in jupyter it works fine

class RaceCar: def init(self, color, fuel_remaining, laps, **kwargs): self.color = color self.fuel_remaining = fuel_remaining self.laps = 0 for key, item in kwargs.items(): setattr(self, key, item) def run_lap(self, length): self.fuel_remaining = fuel_remaining/(length * 0.125) self.laps = self.laps+1

racecar.py
class RaceCar:
    def __init__(self, color, fuel_remaining, laps, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0
        for key, item in kwargs.items():
            setattr(self, key, item)
    def run_lap(self, length):
        self.fuel_remaining = self.fuel_remaining-length * 0.125
        self.laps = self.laps+1

Hi there, Oleg Fedorov! It doesn't produce any errors, but it doesn't work as expected, which is slightly different. Right now, you're sending in laps as a parameter, which is what you want. But then you immediately overwrite that to be 0. So it doesn't matter what anyone sends in, it still gets set to 0 regardless. The key here is to set a default value for laps so that if they put in nothing, it will be 0, but otherwise, it will be whatever they gave to the __init__.

Consider the following:

def __init__(self, color, fuel_remaining, laps=0, **kwargs):
        self.color = laps

Hope this helps! :sparkles:
