class RaceCar

I keep getting error: can't find class 'RaceCar', which I can't understand why, I believe everything to be correct

racecar.py
class RaceCar:
    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining

    for key, value in kwargs.item():
        setattr(self, key, value)

One of the really finicky things with python is indentation. It trips me up all the time. Your code is solid, with the exception of the indentation, (these little mistakes right? Lol) Since you want the β€œfor loop” to be inside your init move that over so it becomes encompassed and you’re good too go!

Hope this helps!

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

        for key, value in kwargs.items():
            setattr(self, key, value)

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

i checked everything, made sure everything was where it needed to be but i keep getting a bummer message

Tried posting earlier with more detail but apparently I’m getting a 500 error. Lol don’t want to type out the explanation again. So here is just the answer.

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

        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

[MOD: added ```python formating -cf]

Darryl this is not a correct answer, even if it somehow manages to pass the challenge.

  1. Laps should not be an argument being passed into init we are using **kwargs to pass laps in because we aren't setting a variable for laps directly under class.

  2. Also self.color and self.fuel_remaining need to be directly part of the RaceCar class.

So like this:

class RaceCar:
    color = 'blue'
    fuel_remaining = 10

    # We set the laps to 0 here because if we set it anywhere else all instances
    # would start with how many laps happened last time
    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0

        for key, value in kwargs.items(): # Using kwargs here because we aren't
            setattr(self, key, value) # defining laps in the class but we still need laps

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