Open-source data science course, syllabus not included
The sixth volume of a Chinese open-source textbook series uses its README to promote other books instead of explaining itself.

What it does — This repository hosts 《数据有道》, the sixth book in the Chinese open-source 鸢尾花书 (“Iris Book”) series. By the repository name and topics, it is positioned as a first course in data science—covering visualization, feature engineering, and machine learning—delivered via Jupyter Notebooks. The README, however, offers no outline, lesson list, or even a summary of what Book 6 contains.
The interesting bit — The landing page doubles as a coupon board for three other volumes in the series and a bounty program where proofreaders earn free physical copies. It is a refreshingly direct approach to funding open education, even if it leaves newcomers guessing what this particular book actually teaches.
Key highlights —
- Sixth installment of the 鸢尾花书 open-source book series
- Jupyter Notebook-based, with repository topics spanning data visualization, feature engineering, and machine learning
- Permanently available open-source resources (per the README)
- Rewards contributors who submit corrections with free books
- README provides discount links to companion volumes 《统计至简》, 《数学要素》, and 《矩阵力量》
Caveats —
- The README is essentially silent on Book 6’s own content, structure, or learning objectives
- It is unclear from the sources how this volume differs from the other linked books
Verdict — Worth exploring if you read Chinese and want open-source data science notebooks, but only if you are comfortable digging past a README that offers no map of the curriculum. If you need a detailed syllabus upfront, this landing page will frustrate you.
