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# check if image-last-modified-date is outdated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