## Code Before:

class Node(object): # define constructor
	def __init__(self, value):
		self.value = value
		self.next = None

## Instruction:
Add initialization to linked list class
## Code After:

class Node(object): # define constructor
	def __init__(self, value):
		self.value = value
		self.next = None

class LinkedList(object):
	def __init__(self, head=None):
		self.head = head
