用Python随便生成一段尾插法的代码

这里是一个简单的尾插法示例：

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

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

    def append(self, data):
        new_node = Node(data)
        if not self.head:
            self.head = new_node
            return
        curr_node = self.head
        while curr_node.next:
            curr_node = curr_node.next
        curr_node.next = new_node

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

# Example Usage
linked_list = LinkedList()
linked_list.append(1)
linked_list.append(2)
linked_list.append(3)
linked_list.print_list()

运行结果：

1
2
3
