如何使用python实现删除文件或文件夹实例

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:

#

 

# t = common()

# foldername = r'temp'

# t.deletefolder(foldername)

#

 

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

#

#example:

#

 

# t = common()

# foldername = r'tempfile.txt'

# t.deletefile(filename)

#

 

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

#

#example:

#

 

# t = common()

# foldernamelist = [r'temp1', r'temp2']

# t.deletefolders(foldernamelist)

#

 

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

#

#example:

#

 

# t = common()

# foldernamelist = [r'temp1.txt', r'temp2.txt']

# t.deletefiles(filenamelist)

#

 

def deletefiles(self, filenamelist):

for filename in filenamelist:

self.deletefile(filename)

return

op = deleter()

op.deletefile('a.txt')

# failed to delete file: a.txt
