I am not sure why this isn't working.

In this challenge, we're asked to make a simple class, here is what the challenge info says: "OK, let's combine everything we've done so far into one challenge! First, create a class named RaceCar. In the init for the class, take arguments for color and fuel_remaining. Be sure to set these as attributes on the instance. Also, use setattr to take any other keyword arguments that come in."

racecar.py
class RaceCar:
    color = "blue"
    fuel_remaining = 100

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)

It wants you to set the values on the instance, which means within __init__

The method I have used at the end is one that will unpack the extra arguments being passed in and set them as attributes.

class RaceCar:
    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.__dict__.update(kwargs)

i never leaned dict....;-;
