how do i call this "run_lap" method and increment "laps" attribute by 1 when its called help!

i don't know how to call the run_laps method and when its called how to increment the run_laps method

racecar.py 
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,laps)
            self.laps = 0
        def run_lap(self,length):
            length = fuel_remaining - (length*0.125)
            return self.length
            if self.lenght = true:
                run_lap += 1

It looks like there's a few issues to resolve:

  • check indentation — the "def" line should start in the same column as the other "def" line in the class
  • the "self." prefix should not be used on parameters
  • but the "self." prefix is needed on the class attributes (like "fuel_remaining")
  • the "run_lap" method does not need to "return" anything
  • check spelling ("lenght " instead of "length")
  • the increment does not need a conditional ("if")
  • the item to be incremented is "self.laps" instead of "run_lap"

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

i've done this but it still shows error!

When posting code to the forum, use Markdown formatting to preserve the appearance, particularly indentation!

But it looks like you have not yet implemented several of the suggestions.
