如何将节点保存到数组中

# 定义一个节点类
class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

# 定义一个链表类
class LinkedList:
    def __init__(self):
        self.head = None

    # 将节点添加到链表末尾
    def append(self, data):
        new_node = Node(data)
        if self.head is None:
            self.head = new_node
        else:
            current = self.head
            while current.next is not None:
                current = current.next
            current.next = new_node

    # 将链表节点存储到数组中
    def to_array(self):
        result = []
        current = self.head
        while current is not None:
            result.append(current.data)
            current = current.next
        return result

# 创建一个链表并添加节点
linked_list = LinkedList()
linked_list.append(1)
linked_list.append(2)
linked_list.append(3)

# 将链表节点存储到数组中
node_array = linked_list.to_array()
print(node_array)  # 输出: [1, 2, 3]
