How come newNode object in insert method is having different heap addresses while the newNode reference variable is same ?

Question

# A single node of a singly linked list
class Node:
# constructor
def __init__(self, data = None, next=None):
self.data = data
self.next = next

# A Linked List class with a single head node
class LinkedList:
def __init__(self):
self.head = None

# insertion method for the linked list
def insert(self, data):
newNode = Node(data)
if(self.head):
current = self.head
while(current.next):
current = current.next
current.next = newNode
else:
self.head = newNode

# print method for the linked list
def printLL(self):
current = self.head
while(current):
print(current.data)
current = current.next

# Singly Linked List with insertion and print methods
LL = LinkedList()
LL.insert(3)
LL.insert(4)
LL.insert(5)
LL.printLL()

Answer 1

I m talking about object newNode in insert method , i m asking how come that newNode is getting different heap addresses on each insert method call since the object name (newNode) is same each time.

Answer 2

How come 1st and 3rd object heap address r coming same? !! Python programming doubt please help

Class Test:
def __init__(self,data):
self.data = data
print(self.data)
obj = Test(5)
print(obj)
obj = Test(6)
print(obj)
obj = Test(7)
print(obj)

Then why these obj objects are not getting different heap addresses coz output heap address of 1st and 3rd object is coming same
