@SigureMo 自查完成：本 PR 将以下 3 个文件的 docstring 示例标记从 code-block:: python 迁移为 code-block:: pycon，并已执行 ruff format。

• python/paddle/framework/io.py
• python/paddle/framework/random.py
• python/paddle/utils/dlpack.py

仅文档示例标记调整，无运行逻辑改动。辛苦 review 🙏

已处理本轮 3 条 review 建议：补齐 pycon 多行示例 trailing comma，完成格式化并推送更新（commit: 5fa74e2）。@SigureMo 麻烦复查，感谢。
