Is the reason that we don't have to explicitly import the Node class because it is referenced in the LinkedList class?

No more details required, except this is a mandatory field.

Hi Aaron, Both classes are defined on the same python file. So, there is no need to import anything.

Hello there!, i'm doing these exercises with javascript but the following logic should remain the same for both languages, you only need to import the LinkedList basically because that LinkedList class is the one who manages the Node class internally and you don't need to make use of it.
