Linked List in Python

Working on building a generic Linked List in Python from the Linked List article at CodeFellows.
Here it is...
class Node(object): def __init__(self, data): self.data = data self.nextNode = None class linkedList(object): def __init__(self, head=None): self.head = head def insert(self, node): if not self.head: self.head = node else: # set new nodes pointer to old thread node.nextNode = self.head # reset head to new node self.head = node def search(self, lList, Node): if self.head == Node: return self.head else: if lList.head.nextNode: self.search(linkedList(lList.head.nextNode), Node) else: raise ValueError("Node not in Linked List") def size(self): current = self.head size = 0 while current is not None: size += 1 current = current.nextNode return size def delete(self, node): if self.size() == 0: raise ValueError("List is empty") else: current = self.head previous = None found = False while not found: if current == node: found = True elif current is None: raise ValueError("Node not in Linked List") else: previous = current current = current.nextNode if previous is None: self.head = current.nextNode else: previous.nextNode = current.nextNode

Here is the code for using the above list to make a LinkedList and to insert some test data:
myList = linkedList() for x in range(1,10): y = Node(x) myList.insert(y) print(myList.size())
