这篇文章主要介绍了python删除过期文件的方法,涉及Python日期与文件的相关操作技巧,需要的朋友可以参考下
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- # check if image-last-modified-date is outdated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
希望本文所述对大家的Python程序设计有所帮助。
