import os folder_list = ['/path/to/folder1', '/path/to/folder2', '/path/to/folder3'] for folder_path in folder_list: for sub_folder in os.listdir(folder_path): sub_folder_path = os.path.join(folder_path, sub_folder) if os.path.isdir(sub_folder_path): for file_name in os.listdir(sub_folder_path): file_path = os.path.join(sub_folder_path, file_name) if os.path.isfile(file_path): print('{}\t{}'.format(os.path.basename(os.path.dirname(folder_path)), file_name))将这个代码修改，只读取txt格式的文件

好的，以下是修改后的 Python 代码：

import os

folder_list = ['/path/to/folder1', '/path/to/folder2', '/path/to/folder3']

for folder_path in folder_list:
    for sub_folder in os.listdir(folder_path):
        sub_folder_path = os.path.join(folder_path, sub_folder)
        if os.path.isdir(sub_folder_path):
            for file_name in os.listdir(sub_folder_path):
                file_path = os.path.join(sub_folder_path, file_name)
                if os.path.isfile(file_path) and file_name.endswith('.txt'):
                    print('{}\t{}'.format(os.path.basename(os.path.dirname(folder_path)), file_name))

你需要将代码中的 `/path/to/folder1`、`/path/to/folder2` 和 `/path/to/folder3` 替换成你想要遍历的文件夹路径列表，然后运行即可。代码会遍历所有子文件夹，只读取其中的 txt 格式文件，并输出一列来显示文件属于哪个一级文件夹，只显示出一级文件夹。
