我是Python的初学者。我想将文件从一个未创建的子目录（从目录1）移动到另一个子目录（目录2）。这该怎么做？

#dir data 1 is source which contain subdir_A and subdir_B
dir_data_1:
 -subdir_A:
    -img_1.jpg
    -img_2.jpg
 -subdir_B:
    -img_3.jpg
    -img_4.jpg

#dir data 2 is the target where the files should be moved and also include subdir name
(this is what I want at the end)
dir_data_2:
 -subdir_A:
    -img_1.jpg
    -img_2.jpg
 -subdir_B:
    -img_3.jpg
    -img_4.jpg

到目前为止，我编写的代码看起来像这样

import os
import shutil

src = 'datasetx/x/'
dst = 'datasety/'

for root,dirs,files in os.walk(src):
    k = os.makedirs(os.path.join(dst,os.path.basename(root))
    for file_ in files:
        shutil.move(file_,k)

你能指导我吗？谢谢
