Discussion on: Dijkstra's algorithm in python: algorithms for beginners

Using Python object-oriented knowledge, I made the following modification to the dijkstra method:

return the distance between the nodes

    distance_between_nodes = 0
    for index in range(1, len(path)):
        for thing in self.edges:
            if thing.start == path[index - 1] and thing.end == path[index]:
                distance_between_nodes += thing.cost
    return distance_between_nodes       
    # return path
