Edit: just noticed that i was assigning none to a new variable n and i thought i was setting the address to None with the following code,lol !

while n.next:
n=n.nexr
n=None

Answer 1

Traverse until next of next is none.
Delete next

def delete_from_last(self):
n=self.head
while n.next.next:
n=n.next
n.next = None

additionally check if head has next(otherwise head is last)
