shutil 其他模块

shutil.copyfile( src, dst) #从源src复制到dst中去。 如果当前的dst已存在的话就会被覆盖掉

shutil.move( src, dst) #移动文件或重命名

shutil.copymode( src, dst) #只是会复制其权限其他的东西是不会被复制的

shutil.copystat( src, dst) #复制权限、最后访问时间、最后修改时间

shutil.copy( src, dst) #复制一个文件到一个文件或一个目录

shutil.copy2( src, dst) #在copy上的基础上再复制文件最后访问时间与修改时间也复制过来了，类似于cp –p的东西

shutil.copy2( src, dst) #如果两个位置的文件系统是一样的话相当于是rename操作，只是改名；如果是不在相同的文件系统的话就是做move操作

shutil.copytree( olddir, newdir, True/Flase) #把olddir拷贝一份newdir，如果第3个参数是True，则复制目录时将保持文件夹下的符号连接，如果第3个参数是False，则将在复制的目录下生成物理副本来替代符号连接
