Learning to describe problems is hard, but it is an important part of learning how to code.
Also, the more you say, the more we can help!

Hi, welcome to the forum!
We see you have posted some code but did you have a question?

(You have not filled out the “Tell us what’s happening:” field above)

Hi @vsudhakarnaidu31

You should create a for loop to iterate over graph inside the shortest_path function.

Try iterating over graph instead of

Happy coding
