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> 
  #  T = Common() 
  #  FolderName = r'Temp' 
  #  T.DeleteFolder(FolderName) 
  #</pre> 
  def DeleteFolder(self, FolderName): 
    '''''delete files and folders''' 
    for Item in os.listdir(FolderName): 
      TempPath = os.path.join(FolderName, Item) 
      if os.path.isfile(TempPath): 
        self.DeleteFile(TempPath) 
        pass 
      elif os.path.isdir(TempPath): 
        self.DeleteFolder(TempPath) 
        pass 
      else: 
        self.Log("Not a file or folder: %s" % (FolderName)) 
        pass 
      pass 
 
    try: 
      os.rmdir(FolderName) 
      self.Log("Folder deleted: %s" % (FolderName)) 
    except: 
      self.Log("Failed to delete folder: %s" % (FolderName)) 
      pass 
 
    return 
 
 
  ## Delete a file 
  # @param FileName file to delete 
  #<br/> 
  #Example: 
  #<pre> 
  #  T = Common() 
  #  FolderName = r'TempFile.txt' 
  #  T.DeleteFile(FileName) 
  #</pre>

    except: 
      self.Log("Failed to delete file: %s" % (FileName)) 
      pass 
    return 
 
  ## Delete a list of folders 
  # @param FolderList a list of folder to delete 
  #<br/> 
  #Example: 
  #<pre> 
  #  T = Common() 
  #  FolderNameList = [r'Temp1', r'Temp2'] 
  #  T.DeleteFolders(FolderNameList) 
  #</pre> 
  def DeleteFolders(self, FolderNameList): 
    for FolderName in FolderNameList: 
      self.DeleteFolder(FolderName) 
    return 
 
  ## Delete a list of files 
  # @param FolderList a list of files to delete 
  #<br/> 
  #Example: 
  #<pre> 
  #  T = Common() 
  #  FolderNameList = [r'Temp1.txt', r'Temp2.txt'] 
  #  T.DeleteFiles(FileNameList) 
  #</pre>

    for FileName in FileNameList: 
      self.DeleteFile(FileName) 
    return

Op.DeleteFile('a.txt') 
# Failed to delete file: a.txt
