python实现删除文件或文件夹

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
