Confused

I am confused. Can someone explain to me what I am doing wrong please.

racecar.py 
class RaceCar(color, fuel_remaining):
    def __init__(self, color, fuel_remaining, **kawargs):
        self.color = red
        self.fuel_remaining = guage
        for key, value in kwargs.items():
            setattr(key, value, **kwargs)

Check out the teachers notes on the Method Arguments video and compare it to your code.

Here's 4 things that look wrong - is that what you are asking about?

  1. Looks like the spelling of kwargs isn't consistent
  2. Assignment of self.color and self.fuel_remaining is not being set with the parameter values
  3. Why are you passing **kwargs to setattr()? You're already passing the key and value, also don't you need self in there?
  4. Are you sure you want to have parameters in the class definition.

You're getting kind of close, but:

  • "RaceCar" doesn't inherit from other classes, so it doesn't need terms in parentheses
  • you have "kawargs" (with an extra "a") instead of "kwargs"
  • nothing named "red" has been defined .. did you mean "color"?
  • nothing named "guage" has been defined ... did you mean "fuel_remaining"?
  • the "setattr" function doesn't need a "**kwargs" argument
  • but it does need a "self" argument

Your syntax is wrong. Here are some resources:
