Learn Algorithm Design by Building a Shortest Path Algorithm - Step 23

Tell us what’s happening:

Everything seems okay to me but the test isn’t passing

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 = []
    distances = {}
    for node in graph:
        unvisited.append(node)
        if node == start:
            distances[start] = 0

Then assign 0 to that node inside the distances dictionary.

Just double check what you are assigning to
