'Use Python' Sum of Nodes

You are given a Linked List, LL$1,$ and an array, dist. Write a method sum$\_$dist$($list$,$ arr$)$ that takes a Linked List and an array as parameters. This method sums the node elements in the linked list that are away from the head by the elements in the array and returns the sum. Assume the Node class has only elem and next variable. No need to write Node class and driver code.
