Python Development Techdegree Student 9,648 PointsProblem with the challenge (part 2/3).
Hello Guys, I am a little stuck in this challenge, I do not know how to add +1 to the "laps" attribute once the method "run_lap" is called. I tried many things, but I miss something obviously. My code is attached.
class RaceCar:
laps = 0
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, lengt, laps):
self.length = fuel_remaining - (length * 0.125)

- the parameter name spelled "lengt" instead of "length"
- the reference to "fuel_remaining" needs a "
self.
" prefix - the fuel calculation should update the remaining fuel instead creating a new "length" attribute
And adding to the laps can be done like this:
self.laps += 1

Python Development Techdegree Student 9,648 PointsSteven, thank you so much for the advice. It was very helpful.
However t may sound, but with this challenge I completely understood the logic behind (self.).
Sometimes challenges are way to important not to be taken seriously. Thanks again.
