Questions regarding updating about_py.md and handling LTR fragments in RTL layout

先查看 about_py.md 以及 getting_started.md 中现有的 RTL 处理，然后检查所列英文片段的预览行为。明确预期结果是更新文档、手动进行 LTR 修复，还是更改 theme；当达成一致的方向，并且波斯语讲义文件中的渲染保持一致时，即视为完成。

Hi @mmcky
I have two questions as I continue reviewing the Persian lecture files:

1.Update of about_py.md
Based on the updates you recently applied to the other lectures — including the new conventions for figure directives, LaTeX alignment — the overall structure of the lecture series has now become consistent and standardized.
The about_py.md lecture, however, still follows the older structure. I wanted to ask whether you are planning to update this lecture as well so that it aligns with the new conventions.
If this update is planned, will you be handling it, or would you prefer that I apply the necessary changes and open a PR?

2.LTR content inside RTL text
Some English fragments need to remain left-to-right within the Persian (RTL) text, for example:

• file extensions (e.g., .ipynb)
• function names (e.g., append())
• assignments or short code expressions (e.g., ϵ_values = [])

These currently render right-to-left in the preview.
Should I continue fixing these manually (as I did in getting_started.md by reversing placement), or do you expect that the theme will eventually handle such cases automatically?

Thank you, and please let me know how you would like me to proceed.
