Here we go again! List comprehensions. This time with dictionaries. Please help.

### 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 = {}
paths = {key:[] for (key) in graph}
print(f'Unvisited: {unvisited}\nDistances: {distances}')
shortest_path(my_graph, 'A')
/* User Editable Region */
```
