打印windows目录下所有mp4文件的建立时间和文件大小

import time
import os
import re

p = re.compile(r".mp4")
os.chdir('D:\BaiduYunDownload\python')
with open('file.txt','w') as file:
    for r,d,f in os.walk('D:\BaiduYunDownload\python'):
        for i in f:
#           if i.endswith(".mp4"):
            if p.search(i):
                temp = time.localtime(os.path.getctime(i))
                size = (os.path.getsize(i)) / 1024 / 1024
                print ("%s 被访问的时间是:" % i,time.strftime("(%Y-%m-%d %H:%M:%S)",temp),"文件大小为:%dMB\n" % size)
                file.writelines("%s 被访问的时间是:" % i+time.strftime("(%Y-%m-%d %H:%M:%S)",temp)+"文件大小为:%dMB\n" % size)
