python删除过期文件的方法
本文实例讲述了python删除过期文件的方法。分享给大家供大家参考。具体实现方法如下：
#removealljpegimagefilesofanexpiredmodificationdate=mtime
#youcouldalsousecreationdate(ctime)orlastaccessdate(atime)
#os.stat(filename)returns(mode,ino,dev,nlink,uid,gid,size,atime,mtime,ctime)
#testedwithPython24vegaseat6/7/2005
importos,glob,time
root='D:\\Vacation\\Poland2003\\'#onespecificfolder
#root='D:\\Vacation\\*'#orallthesubfolderstoo
#expirationdateintheformatYYYY-MM-DD
xDate='2003-12-31'
print'-'*50
forfolderinglob.glob(root):
printfolder
#here.jpgimagefiles,butcouldbe.txtfilesorwhatever
forimageinglob.glob(folder+'/*.jpg'):
#retrievesthestatsforthecurrentjpegimagefile
#thetupleelementatindex8isthelast-modified-date
stats=os.stat(image)
#putthetwodatesintomatchingformat
lastmodDate=time.localtime(stats[8])
expDate=time.strptime(xDate,'%Y-%m-%d')
printimage,time.strftime("%m/%d/%y",lastmodDate)
#checkifimage-last-modified-dateisoutdated
ifexpDate>lastmodDate:
try:
print'Removing',image,time.strftime("(olderthan%m/%d/%y)",expDate)
#os.remove(image)#commentedoutfortesting
exceptOSError:
print'Couldnotremove',image
