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    # check if image-last-modified-date is outdated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