Python Linked List basics

Basic linked list structure
class node:
    def __init__(self,data,next=None):
        self.data=data
        self.next=next

class linked_list:
    def __init__(self):
        self.head=None

    def insert(self,data):
        new_node=node(data)
        new_node.next=self.head
        self.head=new_node

    def appending(self,data):
        cur = self.head
        while cur.next:
            cur = cur.next
        cur.next=node(data)

    def printing(self):
        cur=self.head
        while cur.next:
            print(cur.data)
            cur = cur.next
        print(cur.data)

LL=linked_list()
LL.insert(1)
LL.appending(2)
LL.appending(3)
LL.printing()
