如何执行完整的递归目录和文件扫描？

import os

def scan_directory(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            try:
                file_size = os.path.getsize(file_path)
                file_mtime = os.path.getmtime(file_path)
                print(f"文件名：{file_path}，大小：{file_size}，修改时间：{file_mtime}")
            except Exception as e:
                print(f"无法读取文件属性：{file_path}，错误信息：{e}")

        for dir in dirs:
            dir_path = os.path.join(root, dir)
            try:
                dir_size = os.path.getsize(dir_path)
                dir_mtime = os.path.getmtime(dir_path)
                print(f"目录名：{dir_path}，大小：{dir_size}，修改时间：{dir_mtime}")
            except Exception as e:
                print(f"无法读取目录属性：{dir_path}，错误信息：{e}")

if __name__ == "__main__":
    scan_directory("/path/to/scan")
