racecar.py challenge 2 - "bummer: try again"

really confused why this isnt working. can anyone advise?

racecar.py
class RaceCar:
    laps = 0
    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)

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

after copying and pasting into an IDE, i think there are hidden characters screwing with the white spacing. literally the code is fine and the spacing APPEARS to be fine but there are hidden characters that are failing the code.

can the devs at team treehouse please address this infuriating issue. or at the very least, give us a real error message

I'm not sure what you mean. I copy/pasted your code just as is and it passed.

Steven Parker this is from my execution after just copying and pasting. After seeing this error i removed all spacing (and from vscode i can tell its visually 2 tabs) and then retabbed, boom worked.

ive actually seen this issue before too. its probably because im using chrome os and im guessing they dont test much on chrome os yet

>>> from racecar import RaceCar
Traceback (most recent call last):

Your code looks good to me. :+1:

So I tried pasting it directly into the challenge, and it passed task 1 and task 2!

If you're getting a "false failure", I've heard that restarting your browser can help.

looks like you just need to add the laps attribute to your class, in the init

self.laps = 0

That's task 3, he's still on task 2. If it were task 3 the error message would be different.
