本文实例讲述了Python实现文件按照日期命名的方法。分享给大家供大家参考。具体实现方法如下：
这里实现文件按照创建的时期批量重命名的功能
# -*- coding: utf-8 -*-
import os
import time
import datetime
rootDir = "I:/1/"
dic={}
for dirName,subDirs,fileList in os.walk(rootDir):
print dirName
for fn in fileList:
fnpath=dirName+fn
st = os.stat(fnpath)
mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime = st
# print mtime
t=time.ctime(mtime)
d_from_t = datetime.datetime.fromtimestamp(mtime)
dic[fnpath]=d_from_t.strftime('%Y-%m-%d%H:%M:%S')
# print fnpath+"- last modified:", d_from_t.strftime('%Y-%m-%d %H:%M:%S')
pass
for x in dic:
# p=os.path.splitext(x)[0]
p=os.path.dirname(os.path.abspath(x))
ext=os.path.splitext(x)[1]
# tpath=p+"/"+dic[x]+ext
# print tpath
# print os.path.dirname(os.path.abspath(p))
nname=os.path.join(rootDir,dic[x]+ext)
# print p,ext
print "os.rename('"+x+"','"+nname+"'')"
os.rename(x,nname)
pass
希望本文所述对大家的Python程序设计有所帮助。
