python 实现删除文件或文件夹实例详解

python 实现删除文件或文件夹

      最近自己学习Python 的知识，自己学习抓取网页的内容知识等，在学习的时候Python 删除文件夹或者文件知识的时候，觉得本篇内容不错，推荐给大家。

实例代码，仔细看注释明细：

    #-*- coding: UTF-8 -*- 
    # 有时候要删除文件夹里文件或文件夹 
    # 这个小类用来删除文件或文件夹还是相当有用的 
    # 删除文件时有时希看到删除的结果，于是就有了这个Deleter了 
    # 下面的一些文件注释用的是Doxygen的样式 
    # 用了英文，先就不改回中文吧。 
    class Deleter(): 
      def __init__(self, ToPrint=True, Logger=None): 
        self.Logger = Logger 
        self.ToPrint = ToPrint 
        return 

      def Log(self, Str): 
        if self.Logger: 
          self.Logger.Log(Str) 
        if self.ToPrint: 
          print Str 
        return 

      ## Delete a folder 
      # @param FolderName folder to delete 
      #<br/> 
      #Example: 
      #<pre>

      #  FolderName = r'Temp' 
      #  T.DeleteFolder(FolderName) 
      #</pre>

      # @param FolderList a list of folder to delete 
      #<br/> 
      #Example:

      ## Delete a list of files 
      # @param FolderList a list of files to delete
