凑数吧

class Solution:
    def removeNthFromEnd(self, head: ListNode, n: int) -> ListNode:
        lists = []
        arrow = head
        while arrow:
            lists.append(arrow)
            arrow = arrow.next
        print()
        if -n-1>=-len(lists):
            lists[-n-1].next = lists[-n].next
        else:
            return head.next
        return head
