. We can say that the Electriccar class inherits these same attributes from the normal Car class.The realization of our Car class:Once initialized, we can use all of the created instance variables. That's great.In Python, we inherit the parent class as a child parameter. The Electriccar class can inherit our car class.It's so simple. We do not need to implement any other method, because this class has completed the inheritance of the parent class (inh
