如何递归删除以"._"开头的文件夹中的所有文件？

import os

def delete_files_with_prefix(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.startswith("._"):
                file_path = os.path.join(root, file)
                os.remove(file_path)
        for dir in dirs:
            if dir.startswith("._"):
                dir_path = os.path.join(root, dir)
                delete_files_with_prefix(dir_path)
                os.rmdir(dir_path)

# 调用函数删除指定目录下以"._"开头的文件夹中的所有文件
delete_files_with_prefix("/path/to/directory")
