Sorry, but since this is a method of a BinaryTree instance, there has to be an instance of the tree in order to call the method in the first place. myTree.preorder()
This is different from listing 2 where the tree is passed as a parameter preorder(myTree)
In the first case if myTree is None then you will get an error "NoneType object has no method preorder"
