I am getting "Bummer Try again". This code is good, so not sure why this is failing with the interpreter.

I am getting "Bummer Try again" on racecar.py part 2 . This code is good, so not sure why this is failing with the interpreter. Any help is appreciated!

class RaceCar:

    def __init__(self, color=None, fuel_remaining=None, 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.laps += 1
        return self.fuel_remaining -= (length * 0.125)

Take out the return from the line where you assign a new value to self.fuel_remaining.

(In Python, assignment is a statement not an expression and so it is invalid to attempt to return it)
