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：

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        # check if image-last-modified-date is outdated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