Project 3: Map-based Routing Application
User Interaction and Input Handling
A practical routing application should interact with the user, allowing them to specify start and end locations. We'll implement a simple way to handle this.
Example Code:
def get_route(graph, start, end):
distances = dijkstra(graph, start)
return distances[end]
# Example User Interaction
start_location = input("Enter the start location: ")
end_location = input("Enter the destination: ")
try:
route_distance = get_route(graph, start_location, end_location)
print(f"The shortest distance from {start_location} to {end_location} is {route_distance}")
except KeyError:
print("Invalid location entered.")This code snippet allows users to input their desired start and end locations and outputs the shortest distance between them.
