如何在python中复制文件夹结构的第一层？

Question

Consider following folder structure

├─a
│  ├─a1
│  ├─a2
|      ├─a2_1
│      ├─a2_2
│  └─a3
│      ├─a3_1
│      ├─a3_2
│      └─a3_3

Is there any way to copy the folders a1, a2, a3 without any subfolders or files into a folder b so it would look like this:

├─b
│  ├─a1
│  ├─a2
|  └─a3

Answer 1

If you don't want to copy subdirectories or files, you aren't really performing any copy at all. All you need to do is to create directories with same names as in the input folder.

import os

adir = 'a'
bdir = 'b'

for fn in os.listdir(adir):
    if os.path.isdir(os.path.join(adir, fn)):
      os.mkdir(os.path.join(bdir, fn))

Answer 2

This should work

import os

for name in os.listdir("<PATH_TO_A>"):
    if os.path.isdir("<PATH_TO_A>" + name):
        os.mkdir("<PATH_TO_B>" + name)
