how do you reverse a linked list in python

Use either an iterative pointer-reversal approach or a recursive approach. The standard iterative version is the most common and runs in (O(n)) time with (O(1)) extra space:
class ListNode:
def __init__(self, val=0, next=None):
self.val = val
self.next = next
def reverse_list(head):
prev = None
curr = head
while curr:
nxt = curr.next
curr.next = prev
prev = curr
curr = nxt
return prev
If you already have a Python list, reversing it is simpler with slicing: items[::-1], but that is not a linked list reversal.
