Why is the 'head' in a linked list set to none?

hi I been trying to teach myself about data structures, and started off with reading stuff about linked lists. Im still new to python in general, but I knew the basics of classes and the syntax and all that, so decided why not just try learning this. Anyways, I got up to this part where I create a linked list class, and I know that the ‘head’ part of a linked list will be the first node, but not too sure as to why it is set to ‘None’. Apologies if this is a dumb question :/

Here is the code to it…

class Node:
  def __init__(self, data): 
    self.data = data
    self.next = None

class LinkedList:
  def __init__(self):  
    self.head = None  #why is this part set to none? 

>Solution :

it’s just intialization part, when linkedlist is intialise you dont expect it to have vaules.

ll = LinkedList()
node = Node(1)
ll.head = node

this will make node as the head of the linked list and you can add the values to it later
