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：

									# remove all jpeg image files of an expired modification date = mtime

									# you could also use creation date (ctime) or last access date (atime)

									# os.stat(filename) returns (mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime)

									# tested with Python24  vegaseat 6/7/2005

									import os, glob, time

									root = 'D:\\Vacation\\Poland2003\\' # one specific folder

									#root = 'D:\\Vacation\\*'     # or all the subfolders too

									# expiration date in the format YYYY-MM-DD

									xDate = '2003-12-31'

									print '-'*50

									for folder in glob.glob(root):

									  print folder

									  # here .jpg image files, but could be .txt files or whatever

									  for image in glob.glob(folder + '/*.jpg'):

									    # retrieves the stats for the current jpeg image file

									    # the tuple element at index 8 is the last-modified-date

									    stats = os.stat(image)

									    # put the two dates into matching format  

									    lastmodDate = time.localtime(stats[8])

									    expDate = time.strptime(xDate, '%Y-%m-%d')

									    print image, time.strftime("%m/%d/%y", lastmodDate)

									    # check if image-last-modified-date is outdated

									    if expDate > lastmodDate:

									      try:

									        print 'Removing', image, time.strftime("(older than %m/%d/%y)", expDate)

									        #os.remove(image) # commented out for testing

									      except OSError:

									        print 'Could not remove', image
