I can't figure out why this isn't working. please help!

racecar.py
class RaceCar:

    def __init__(self, color, fuel_remaining, laps = 0, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = laps


        for key, value in kwargs.items():
            setattr(self, key, value)

    def run_lap(self, length):
        self.fuel_remaining -= (length * .125)
        self.laps += 1

Kirk Waters, you are mixing Tab and Space indentation. This gets corrected in the display of the code, so when the code is copied from the rendered post above it passes. Here are the tabs that should be removed:

Thanks Chris! Just redid the challenge and finally got it! Also learned something new about Tabs and Spaces.

I didn't catch that, so I'm guessing that's something only a moderator can see, right?

Unfortunately, peeking at the raw post source code is only available to moderators. Sorry!

In general, if the cut-and-pasted code passes then it is almost always a tab/space issue.

Good to know! I'll try to remember to suggest checking that next time.
