### Tell us what’s happening:

Not sure how to continue with this step. Could someone give me a hint? thanks

### Your code so far

def shortest_path(graph, start):

unvisited =

distances = {}

for node in graph:

unvisited.append(node)

if node == start:

distances[‘node’] = ‘0’

```
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['node'] = '0'
# User Editable Region
```
