如何将所有子文件夹中的图片移动到 Python 中另一个新的相同文件夹中？

Question

I plan to move the pictures in all subfolders (as shown in the picture) under the train file train/LUAD to another new folder train_new/LUAD . There are .jpg images in each subfolder such as the first one in the picture TCGA-05-4249-01Z-00-DX1.9fce0297-cc19-4c04-872c-4466ee4024db .

import os
import shutil

count = 0

def moveFiles(path, disdir): 
    
    dirlist = os.listdir(path)
    for i in dirlist:
        child = os.path.join('%s/%s' % (path, i))
        if os.path.isfile(child):
            
            imagename, jpg = os.path.splitext(i)    
            shutil.copy(child, os.path.join(disdir, imagename + ".jpg"))
            continue
        moveFiles(child, disdir)

if __name__ == '__main__':
    rootimage = '/content/drive/MyDrive/stat841_final_data/train/LUAD'   
    disdir = '/content/drive/MyDrive/stat841_final_data/train_new/LUAD'       

    moveFiles(rootimage, disdir)

But it does not work. I only got image from the last subfolder except for other subfolders in my new folder train_new/LUAD ...

Just to clarify, you want to move (not copy) images from a nested file structure to a new folder, without nesting?

Be aware that this could overwrite images, if multiple images share the same name!

import pathlib

def move_files(source_folder:pathlib.Path, target_folder:pathlib.Path):
    target_folder.mkdir(parents=True, exist_ok=True)
    for image_file in source_folder.rglob("*.jpg"): # recursively find image paths
        image_file.rename(target_folder.joinpath(image_file.name))

If you are unsure maybe use the copy function first, so you won't lose your original data:

import pathlib
import shutil

def move_files(source_folder:pathlib.Path, target_folder:pathlib.Path):
    target_folder.mkdir(parents=True, exist_ok=True)
    for image_file in source_folder.rglob("*.jpg"): # recursively find image paths
        shutil.copy(image_file, target_folder.joinpath(image_file.name))
