软件测试 / 测试开发丨 Python 学习笔记 之 链表

# 链节点类class ListNode:    def __init__(self, val):        self.val = val        self.next = None

# 链表类class LinkedList:    def __init__(self):        self.head = None
    # 根据 data 初始化一个新链表    def create(self, data):        self.head = ListNode(0)        cur = self.head        for i in range(len(data)):            node = ListNode(data[i])            cur.next = node            cur = cur.next
    # 获取链表长度    def length(self):        count = 0
