How to copy specific files from the sub-folders to a new folder in python?
问题
我需要修改代码，只复制每个子文件夹中的最后一个图像（在这种情况下是第7个图像）到一个新文件夹中。
英文:
I have a folder with several sub-folders, each containing the same number of files (here it is 7). The code that I use at the present copies all the files from the different sub-folders within a main folder, to another new folder.
import os
import shutil
src = r'C:\Users\datasets\testimport os
import shutil
src = r'C:\Users\datasets\test\0'
dest = r'C:\Users\datasets\data_new\test\0'
for path, subdirs, files in os.walk(src):
for name in files:
filename = os.path.join(path, name)
shutil.copy2(filename, dest)
'
dest = r'C:\Users\datasets\data_new\testimport os
import shutil
src = r'C:\Users\datasets\test\0'
dest = r'C:\Users\datasets\data_new\test\0'
for path, subdirs, files in os.walk(src):
for name in files:
filename = os.path.join(path, name)
shutil.copy2(filename, dest)
'
for path, subdirs, files in os.walk(src):
for name in files:
filename = os.path.join(path, name)
shutil.copy2(filename, dest)
I need to modify the code in a way to copy only the last image (i.e. the 7th image in this case) from each sub-folder (windows file arrangement) to a new folder.

import shutil
from glob import glob
src = r'C:\temp\datasets\test\0'
dest = r'C:\temp\datasets\data_new\test\0'
for base, dirs, _ in os.walk(src):
for path in dirs:
files = sorted(glob(os.path.join(base, path, '*')))
if len(files) == 0:
continue
file = files[-1]
filename = os.path.join(path, file)
shutil.copyfile(filename, dest)
'
dest = r'C:\temp\datasets\data_new\testimport os
