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# check if image-last-modified-date is outdated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