Code for def __repr__(self) in GitHub is incorrect.

line 11 and line 15 in the code is not correct... the function should be:

def __repr__(self):
    """
    Return a string representation of the list.
    Takes O(n) time.
    """
    nodes = []
    current = self.head
    while current:
        if current is self.head:
            nodes.append("[Head: %s]" % current.data)
        elif current.next_node is None:
            nodes.append("[Tail: %s]" % current.data)
        else:
            nodes.append("[%s]" % current.data)
        current = current.next_node
    return '-> '.join(nodes)
