本文實例講述了python刪除過期文件的方法。分享給大家供大家參考。具體實現(xiàn)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 6/7/2005import os, glob, timeroot = 'D://Vacation//Poland2003//' # one specific folder#root = 'D://Vacation//*'     # or all the subfolders too# expiration date in the format YYYY-MM-DDxDate = '2003-12-31'print '-'*50for 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'%Y-%m-%d')    print image, time.strftime("%m/%d/%y", lastmodDate)    # check if image-last-modified-date is outdated    if expDate 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

希望本文所述對大家的Python程序設(shè)計有所幫助。
