import osimport shutilimport datetime''' 作用：将目录备份到其他路径。 实际效果： 假设给定目录"/media/data/programmer/project/python" ， 备份路径"/home/diegoyun/backup/“ ， 则会将python目录备份到备份路径下，形如： /home/diegoyun/backup/yyyymmddHHMMSS/python/xxx/yyy/zzz

..

用法:更改这两个参数. backdir:备份目的地. copydirs:想要备份的文件夹.''' def mainLogic(): # add dirs you want to copy backdir = " d:\\test " print (backdir)
