### Tell us what’s happening:

I have an error: You should use the `append()`

method to append `start`

to `paths[start]`

.

Pretty sure that’s what I did, but I may be misinterpreting.

### 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 = list(graph)
distances = {node: 0 if node == start else float('inf') for node in graph}
paths = {node: [] for node in graph}.append(start)
print(f'Unvisited: {unvisited}\nDistances: {distances}')
shortest_path(my_graph, 'A')
/* User Editable Region */
```
