Question

In algorithms, in python, if we have a Node class and a LinkedList class that uses it (and abstracts Node's inner wroking/pointers), how do we iterate over the data of all the Nodes in the LinkedList class without taking away the abstraction of the inner working of Node?

Answer

via a generator function defined in LinkedList class.
here is example (this is not needed to pass this test :) :

class LinkedList(object):
...
    def iter(self):        
        current = self.tail        
        while current:            
            val = current.data            
            current = current.next            
            yield val
