Tell us what’s happening:

i don’t know why this is wrong from what i can see i’m following the instructions

Your code so far

my_graph = {
    'A': [('B', 3), ('D', 1)],
    'B': [('A', 3), ('C', 4)],
    'C': [('B', 4), ('D', 7)],
    'D': [('A', 1), ('C', 7)]
}


# User Editable Region

def shortest_path(graph, start):
    unvisited = []
    for node in my_graph:
        unvisited.append(node)
        


# User Editable Region

Hi @OCode

You should create a for loop to iterate over graph inside the shortest_path function.

Your code is iterating over my_graph

Happy coding
