Developing a JSON Schema I'm looking to create a minimal JSON schema that includes example formulas. The final answer should have an optional header and structured lists organized in sections, ideally sticking to 4-6 bullets each. I should consider producing "Top 8 数字故事金点子" with two lists of 6 bullets each since more topics may be needed. I also want to outline bullet points for "数据口径与抓取," "可视化与发布节奏," and "落地步骤." A short code snippet for computing metrics like PPDA would be useful, but I need to keep it concise.Creating a Digital Story Framework I’m working on a title called 数字故事备选, which includes several sections. In Section 1, I'll detail 6 bullets focused on youth training metrics. Section 2 will cover fan engagement and commercial aspects with another 6 bullets. Section 3 will highlight city impact and community service, aiming for 4-6 points. In Section 4, I’ll put together a catchy template with 6 example headlines. Section 5 will outline data sources with 6 bullet points. Finally, I'll provide a brief Python snippet for calculating U23 minutes.Outlining Implementation Steps In Section 7, I’m focusing on 落地节奏 and will provide 4-6 concise steps. I also need to ask for context: "你们更偏媒体叙事还是俱乐部运营?" and offer options 1, 2, or 3. I should keep everything brief and avoid fabricating 2025 actual numbers; I can only propose examples with placeholders. Finally, I’ll structure the final answer in Chinese to meet the requirements. 这些题都能“用数字讲故事”,适合贯穿整个赛季做系列内容或赞助复盘。挑 3–5 个做主线,其他做月度/阶段性补充。 竞技与青训(赛季主线) 球迷与商业(赞助/票务叙事) 城市与公益(品牌外溢) 标题与选题模板(即拿即用) 数据口径与来源(先定标准,避免口水战) 快速计算示例(两项核心口径) 可视化与发布节奏 落地步骤(本周即可开工) 需要的位置信息/偏好,给我选项数字即可:



import pandas as pd
# events: match_id, player_id, minutes_played, age
df = pd.read_csv('events_minutes.csv')
df['is_u23'] = df['age'] < 23
share = (df.groupby('match_id').apply(lambda g: g[g.is_u23]['minutes_played'].sum() / g['minutes_played'].sum())
.rename('u23_share').reset_index())
SELECT season,
(total_wage + transfer_fees) / NULLIF(league_points,0) AS cost_per_point
FROM finance_season;
