Hi,

when i am trying to test my code i am getting the below error when running the unit test (unittests.test_shortest_path(GraphShortestPath))

this is the error i get:

Process shortest_path:

@erezma

for neighbor, weight in graph.graph[current_vertex].items()

Is the graph a list of a dictionary? It doesn’t make any sense, try to feed your code solution to the LLM and also feed it this error and observe its feedback.

I think the way you are using the graph instance be it a dictionary or a list maybe not right!
