Actually, python is a easiest programming language. It is a dynamically typed language.

(a) Write a function named getShortestPath (graph, from, to) that takes a graph as an input and estimates the shortest distance between a node "from" to a node "to". Example 1: Input Graph: Adjacency list of the following graph. 5 A B 3 10 E D 9. 8. 2 F G 10 From: A To: G Output [(А, В), (В, С), (С, G)] That is, the output shows that the shortest path to reach "G" from "A" is through the nodes B and C.
