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

If you already have a Python list, reversing it is simpler with slicing: items[::-1], but that is not a linked list reversal.
