如何删除双向链表中的特定条目？

class Node:
    def __init__(self, data):
        self.data = data
        self.prev = None
        self.next = None

class DoublyLinkedList:
    def __init__(self):
        self.head = None

    def delete(self, target):
        current = self.head

        # 遍历链表，找到目标条目
        while current:
            if current.data == target:
                break
            current = current.next

        # 如果找到目标条目
        if current:
            # 更新前一个节点的指针
            if current.prev:
                current.prev.next = current.next
            else:
                self.head = current.next

            # 更新后一个节点的指针
            if current.next:
                current.next.prev = current.prev

            # 释放目标条目的内存空间
            del current

    def print_list(self):
        current = self.head
        while current:
            print(current.data)
            current = current.next

# 创建一个双向链表
dll = DoublyLinkedList()

# 添加节点
node1 = Node(1)
node2 = Node(2)
node3 = Node(3)
dll.head = node1
node1.next = node2
node2.prev = node1
node2.next = node3
node3.prev = node2

# 删除特定条目
dll.delete(2)

# 打印链表
dll.print_list()
