python 根据文件创建时间排序

#coding:utf8

import os,time



directory = "d:/scrapy tutorial/"

t = []

d = {}

for filename in os.listdir(directory):

        path = directory + filename

        time1 = time.ctime(os.path.getmtime(path))

        d[time1] = filename

        t.append(time1)

n = 1

for i in sorted(t):

        fn = directory + d[i]

        new_fn = directory + str(n) + '. ' + d[i]

##        if n<10:

##                new_fn = directory + d[i][1:]

##        else:

##                new_fn = directory + d[i][2:]

        os.rename(fn, new_fn)

        n += 1

　　临时写的一个脚本，可以用在那些不支持按时间排序、默认按[0-9a-Z]排序的系统上
