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>
 def DeleteFile(self, FileName):
   try:
     os.remove(FileName)
     self.Log("File deleted: ％s" ％ (FileName))
   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>
 def DeleteFiles(self, FileNameList):
   for FileName in FileNameList:
     self.DeleteFile(FileName)
   return

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