Electric cars don’t have a miles per gallon measurement, seeing as the whole point of them is that they don’t run on liquid fuel… Therefore why does the electric car class have a mpg rating?!

Hi @jarofmoles,

That’s a good catch - It might be better stated as range, which is applicable to both electric and gas vehicles. I’ll look into getting it changed.

Exercise 9 on inheritance says to create a “member variable” for class ElectricCar, yet the actual solution does not actually create a member variable, but rather adds that variable to the def init(): function. That was confusing. The solution comes up wrong if you actually create a battery_type member variable … available to the whole ElectricCar Class.

Hello everybody,

Can someone please explain why do we need to define each member argument inherited by ElectricCar from Car all over again? For me it makes more sense to only add self.battery_type = battery_type after init because the rest of the member variables are inherited from Car.

Thank you in advance!
