Hello,

Can somebody please explain the logic of the solution for step 1?
class LinkedList:
def init(self, value=None):
self.head_node = Node(value)

Why is it correct like this if head_node is not an argument of init()? Moreover, why is self.value = value mentioned?

My code was:
class LinkedList:
def init(self, value=None, head_node):
self.value = value
self.head_node = Node(value)

It didn’t work because I put head_node as an argument for init(). I would appreciate a clear answer so many thanks in advance!
