单项链表项目开发源代码

下面是单向链表的 Python 代码示例：

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

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

    def insert_at_beginning(self, data):
        node = Node(data, self.head)
        self.head = node

    def insert_at_end(self, data):
        if self.head is None:
            self.head = Node(data, None)
            return

        curr = self.head
        while curr.next:
            curr = curr.next

        curr.next = Node(data, None)

    def delete(self, data):
        if self.head is None:
            return

        if self.head.data == data:
            self.head = self.head.next
            return

        curr = self.head
        while curr.next:
            if curr.next.data == data:
                curr.next = curr.next.next
                return
            curr = curr.next

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

这是一个简单的单向链表实现，包含节点类（Node）和链表类（LinkedList）。节点类包含一个数据和一个指向下一个节点的指针，链表类包含一个头指针。链表类包含了插入、删除和打印等方法。
