### Tell us what’s happening:

def shortest_path(graph, start):

unvisited = list(graph)

distances = { node: node == 0 if node == start else node == float(‘inf’) for node in graph}

paths = {node: for node in graph}

print(f’Unvisited: {unvisited}\nDistances: {distances}')

shortest_path(my_graph, ‘A’)

It keeps saying: You should use the dictionary comprehension syntax to give a value to your distances variable.

I do not see the error… Thank you

### 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)]
}

paths = {node: [] for node in graph}
print(f'Unvisited: {unvisited}\nDistances: {distances}')
shortest_path(my_graph, 'A')
