Writing append and search methods (singly-linked list) Given main.py and a Node class in Node.py, complete the LinkedList class in LinkedList.py by writing the append() and search() methods. The search() method should return the Node whose data value matches a given key, and None if the key is not found. The search() method should also set the position of each Node searched in the LinkedList, starting with 1. Ex: If the input is: 12 23 59 37 923 2 12 the output is: 12 found in list at position 1. If the input is: 12 23 59 37 923 2 68 the output is: 68 not found in list.
