# Learn Algorithm Design by Building a Shortest Path Algorithm - Step 43

### Tell us what’s happening:

I’m tried to pass in the instructions correctly at this stage but I end In error and indentation errors specifically, I need help

``````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 = list(graph)
distances = {node: 0 if node == start else float('inf') for node in graph}
paths = {node: [] for node in graph}
paths[start].append(start)

while unvisited:
current = min(unvisited, key=distances.get)

# User Editable Region

for node, distance in graph[current]:
if distance + distances[current] < distances[node]:

# User Editable Region

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

#shortest_path(my_graph, 'A')
