Removing the first node from a linked list
In the previous exercise, you learned how to insert a node at the beginning of a linked list.
In this exercise, you will prepare the code for the remove_at_beginning() method. To do it, you will need to point the head of the linked list to the next node of the head.
Recall the Node() class:
class Node:
def __init__(self, data):
self.data = data
self.next = None
