python 删除过期文件的方法+源码,在本文中涉及的知识有Python日期与文件的相关操作技巧,其主要介绍了python删除过期文件的方法,给有需求的朋友们做个参考。 使用python删除过期文章的具体实现方法如下:

 

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    # check if image-last-modified-date is outdated 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