多级目录树的相关文章

python 小程序 复制目录树

1. 将一个目录树完全复制到另外一个目录下面 import os, sys """ 复制目录树 """ maxloadsize = 1024 * 1024 def copyfile(frompath, topath, maxloadsize= maxloadsize): """ 单个文件的复制 :param frompath:原文件 :param topath: 复制到的文件 :param maxloadsize:

将多级目录打包成zip文件

最近接触PHP,需要用到zip压缩,在网上搜索的一大堆,发现代码都不低于50行.  而且调用还很费事(基础太少看不懂).让我收获的是Php提供有一个ZipArchive类,并有如下方法. bool addEmptyDir( string $dirname ) bool addFile ( string $filename [, string$localname = NULL[, int$start = 0 [, int $length = 0 ]]] ) mixed open( string $

【Lua】Lua + LWT + ExtJS构建目录树

Lua处理后台逻辑,Lua lwt搭建后台程序,ExtJS根据后台传来的json数据构建目录树. 前台html和ExtJS代码不用多讲,直接上代码: treePanel.html 1 <html> 2 <head> 3 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 4 5 <title>ExtJS TreePanel</

php创建多级目录完整封装类操作

创建多级目录函数中调用创建指定下的指定文件的函数: public function create_dir($dir,$mode=0777) { return is_dir($dir) or ($this->create_dir(dirname($dir)) and mkdir($dir, $mode)); } 创建指定路径下的指定文件,string $path(需要包含文件名和后缀),boolean $over_write 是否覆盖文件,int $time 设置时间.默认是当前系统时间,int

Python3 使用基本循环实现多级目录（思路）

一.多级目录设计: 1. 通过循环的方式显示菜单和进入菜单 2. 设置标志位以提供回退上一层菜单 2. 设置标志位以提供退出程序 二.注意要点: 1. 菜单样式,层次关系不要弄混乱 2. 当输入错误时,保留在当前view之下 3. 注意标志位使用之后对其他循环是否有影响,或者需要走其他分支

python【使用简单的os.walk生成目录树】

思路比较简单,使用os.walk 生成目录信息,然后再进行字符串操作,所以没有其他比较复杂的逻辑,但是生成的效果也比较简单,自己看看到是可以哈. 代码如下 # -*- coding: utf-8 -*- ''' Created on July 22, 2017 @author: hehe1234567 ''' import os def simple_dir_tree(ddir): for dirpath,dirnames,filenames in os.walk(ddir.strip(os.s

Linux学习笔记之(2)~linux目录树概览和说明

献给知道mono,了解Jexus,对.net混搭技术感兴趣的朋友. linux目录树如下: 详解:/bin: 系统有很多放置执行档的目录,但/bin比较特殊.因为/bin放置的是在单人维护模式下还能够被操作的指令.在/bin底下的指令可以被root与一般帐号所使用,主要有:cat, chmod, chown, date, mv, mkdir, cp, bash等等常用的指令./boot: 这个目录主要在放置开机会使用到的档案,包括Linux核心档案以及开机选单与开机所需设定档等等. Linux
