I am fixing the Double LInked list function link_nodes(self, node1, node2).
When I run the unittests.test_DoublyLinkedListFixed(DoublyLinkedListFixed) it generates the error
“AttributeError: ‘int’ object has no attribute ‘data’”
I am not sure where is this error is coming from in the unittests.
Could you please advise what could be wrong (either with my implementation of unittests itself) - Thank you
