--description--

Now, call your function passing my_graph and 'A' as the arguments.

--hints--

You should call shortest_path passing my_graph and 'A' as the arguments.

js
({ test: () => assert.match(code, /^shortest_path\s*\(\s*my_graph\s*,\s*("|')A\1\s*\)/m) })

--seed--

--seed-contents--

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

def shortest_path(graph, start):
    unvisited = []
    distances = {}
    for node in graph:
        unvisited.append(node)
        if node == start:
            distances[node] = 0
        else:
            distances[node] = float('inf')
    print(f'Unvisited: {unvisited}\nDistances: {distances}')
