Struggling with Part 2 of the RaceCar Challenge. Could someone share a hint?

The instructions require that we iterate through the number of laps. Should I use self.fuel_remaining in the run_lap method? This is the for loop I put inside the method, using self and length as arguments: 

 def run_lap(self, length, laps):
        laps = 0 
        self.fuel_remaining = self.fuel_remaining - self.length * 0.125
        laps += 1

It looks like you've gotten a bit off track. No, you don't need a loop since "run_lap" always adds just one lap. But you also have some main class issues:

  • the name should not be set to a static value, use the passed argument
  • the color should also not be set to a static value, use the passed argument
  • same thing with fuel_remaining, use the argument
  • "laps" should not be an argument, it is always set to a static value (0)
  • "length" should not be an argument OR a class attribute, it's only used in "run_lap"
  • none of the arguments need defaults

And the original code for "run_lap":

  • should not take "laps" as an argument
  • should not set "laps" to 0
  • should reference "laps" using a "self." prefix
  • should not use "self." on the argument "length"

Thank you so much for reviewing my code. This should help me eliminate a lot of issues.
