王几行xing:【Python-转码刷题】LeetCode 203 移除链表元素 Remove Linked List Elements 提到翻转,熟悉Python的朋友可能马上就想到了列表的 reverse。 1. 读题 2. Python 中的 reverse 方法 list1 = list("abcde") list1.reverse() list1 [Out: ] ['e',
【一】Python学习笔记--List list Python内置的一种数据类型是列表:list。 list是一种有序的集合,可以随时添加和删除其中的元素。 是由一系列按特定顺序排列的元素组成 ,鉴于列表通常包含多个元素,给列表指定一个表… 化境大自在打开知乎App 在「我的页」右上角打开扫一扫 其他扫码方式:微信 下载知乎App 开通机构...
