insert node at beginning of circular linked list in python

Python program for insert node at beginning of circular linked list. Here problem description and other solutions.

#  Python 3 Program 
#  Insert node at beginning of circular linked list

#  Define class of linked list Node
class LinkNode :
	def __init__(self, data, first) :
		self.data = data
		self.next = first
	

class CircularLinkedList :
	#  Class constructors
	def __init__(self) :
		self.head = None
	
	#  Insert node at begining of circular linked list
	def insert(self, value) :
		#  Create a node
		node = LinkNode(value, self.head)
		if (self.head == None) :
			#  First node of linked list
			self.head = node
			node.next = self.head
		else :
			temp = self.head
			#  Find the last node
			while (temp.next != self.head) :
				#  Visit to next node
				temp = temp.next
			
			#  Add node
			temp.next = node
			#  make new head node
			self.head = node
		
	
	#  Display node element of circular linked list
	def display(self) :
		if (self.head == None) :
			print("Empty Linked List")
		else :
			print("  Linked List Element : ")
			#  Get first node
			temp = self.head
			#  iterate linked list
			while (temp != None) :
				#  Display node
				print("  ", temp.data, end = "")
				#  Visit to next node
				temp = temp.next
				if (temp == self.head) :
					#  Stop iteration
					return
				
			
		
	

def main() :
	task = CircularLinkedList()
	#  Add following linked list nodes
	task.insert(8)
	task.insert(7)
	task.insert(6)
	task.insert(5)
	task.insert(4)
	task.insert(3)
	task.insert(2)
	task.insert(1)
	#  Display node
	task.display()

if __name__ == "__main__": main()

Output

  Linked List Element :
   1   2   3   4   5   6   7   8
