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

  #Example:

  def DeleteFolder(self, FolderName):

        self.DeleteFile(TempPath)
