In a kindergarten teacher’s day, a considerable amount of time is spent not on being with the children, but on processing large numbers of documents, spreadsheets, and images — work that involves both repetitive data and formatting operations, and complex business rules that require professional judgment. For these real scenarios, I tried to re-decompose the teacher workflow with Python + AI: Python takes care of business rules, structured data, and automated execution; AI takes care of content generation, rewriting, and suggestions; and the teacher makes the contextual judgments, reviews the content, and makes the final decisions. Taking a daily activity plan as an example, I will share how to start from real needs, combine Python, AI, and teachers’ professional judgment, and explore a human–AI collaborative workflow in practice.
