从python中的多个特定子文件夹复制文件

试试这个

import os
from os.path import join, isfile

BASE_PATH = 'd:/test'
SUBFOLDER = 'Subfolder b'

for folder, subfolders, *_ in os.walk(BASE_PATH):
    if SUBFOLDER in subfolders:
        full_path = join(BASE_PATH, folder, SUBFOLDER)
        files = [f for f in os.listdir(full_path) if isfile(join(full_path, f)) and f.lower().endswith(('.jpg', '.jpeg'))]
        for f in files:
            file_path = join(full_path, f)
            print (f'Copy {f} somewehere')

假设你有两个层次的嵌套

root_dir = './data'
dest_dir = './new_location'
os.listdir(root_dir)

for folder in os.listdir(root_dir):
    folder_path = os.path.join(root_dir, folder)
    if os.path.isdir(folder_path):
        for subfolder in os.listdir(folder_path):
            if subfolder == 'Subfolder B':
                subfolder_path = os.path.join(root_dir, folder, subfolder)
                print(subfolder_path)
                for filename in os.listdir(subfolder_path):
                    file_path = os.path.join(root_dir, folder, subfolder, filename)
                    dest_path = os.path.join(dest_dir, filename)
                    shutil.copy(file_path, dest_path)
                    print("Copied ", file_path, "to", dest_path)

您只需要2个for循环,在内部for循环中,您只需检查文件夹名是否匹配 Subfolder B . 如果是,那么将该目录中的所有文件复制到目标文件夹。

这是一个简短的脚本,应该完成这项工作…

import os

# list all the directories in current directory
dirs = [x[0] for x in os.walk("D:/src")]

for d in dirs:
    ## list all files in A/b/*, B/b/*, C/b/*...
    files_to_copy = os.listdir(os.path.join(d, "b"))  
    for f in files_to_copy:
        if f.endswith(".jpg"):  ## copy the relevant files to dest
            shutil.copy(os.path.join(d, "b", f), os.path.join(dest, f))
