Courses Plus Student 5,467 PointsI felt like I was on a roll until I hit a roadblock with this one...
I created a class named "RaceCar ". Defined the methods that need to be defined. For the " init" method I setup the function the way it's suppose to be ran, but when it comes to the "run_laps " method I got stuck on how I am suppose to reduce the "fuel_remaining" attribute by the length.
Please help...
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(length):
self.fuel_remaining = fuel_remaining - (length * 0.125)
laps += 1

You forgot to include self in the run_lap method declaration and include self in front of every internal data reference. Every method in a class needs to have self to reference its internal data.
Keep up the good work on your learning journey. Python is an amazing language and valuable to so many development roles.
class RaceCar:
laps = 0
def __init__(self, color, fuel_remaining, **kwargs):
self.laps = 0 # added this too.
self.color = color
self.fuel_remaining = fuel_remaining
for key, value in kwargs.items():
setattr(self, key, value)
def run_lap(self, length):
# make sure to include self to reference the internal data
self.fuel_remaining = self.fuel_remaining - (length * 0.125)
self.laps += 1
