'Can't find RaceCar' - but it's right there!

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."

It gives me an error saying it can't find RaceCar even though it's right there in the code. I'm pretty sure I've done what it wants me to do, what am I doing 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)

A Couple Things:

1: You left color and fuel_remaining hanging without giving it a default string (for color) or integer (for fuel). Fix that bit first. It's what's causing RaceCar to "not be found." For example:

color = "your_color"
remaining_fuel = 100

2: This error's a little harder to spot. In your line:

for key, value in kwargs.items:

The method .items is written incorrectly. It should be .items() instead. So, that line should read as:

for key, value in kwargs.items():

After that, you should be good to go. Best of luck!

Works like a charm, thanks Chrisee!
