📝 Translation Quality

Criterion	Score
Accuracy	9/10
Fluency	9/10
Terminology	9/10
Formatting	9/10
Overall	9/10

Summary: The translation of the three modified sections (Slicing and Reshaping Data, Merging Dataframes and Filling NaNs, and Exercises) is of high quality, accurately conveying technical pandas concepts with natural Chinese phrasing. Terminology is consistent with standard data science translation conventions, and all code blocks, headings, and MyST directives are properly preserved. No critical syntax errors were found. Minor stylistic improvements could be made but do not detract from overall clarity or correctness. Technical terms like MultiIndex, DataFrame, pivot_table, groupby are consistently preserved in English (standard practice for code-related terms) while surrounding prose is fluently translated into Chinese. Complex explanations of merge types (left/right/inner/outer join) are accurately and clearly translated, preserving the logical structure of the original. Code comments are appropriately translated while code syntax remains untouched, maintaining functional integrity. The translation of nuanced explanations about stacking/unstacking MultiIndex levels is accurate and reads naturally in Chinese.

Suggestions:

• Merging Dataframes and Filling NaNs section: 'This is illustrated by the red shading in the following diagram' → '下图中的红色阴影部分说明了这一点' is accurate, but the figure caption context could be slightly clearer; minor, not critical.
• Slicing and Reshaping Data section: 'measured in 2015 US dollars' translated as '以 2015 年美元计价' is accurate but placed slightly differently in sentence structure compared to source flow; consider '以 2015 年美元计价的各国和各时间段每小时实际最低工资' for smoother reading, though current version is acceptable.

Summary: The three URL changes (realwage.csv, countries.csv, employ.csv) from the old repo path to the new lecture-python-programming path were correctly synced in the same three locations in the target document, with no other unintended changes.

Pull request overview

This translation-sync PR updates the Chinese pandas_panel lecture to remove the remaining runtime dataset links that still referenced the retired QuantEcon/lecture-python repository, switching them to the current QuantEcon/lecture-python-programming repository.

Changes:

• Replaced three raw.githubusercontent.com/QuantEcon/lecture-python/master/... CSV URLs with QuantEcon/lecture-python-programming/main/lectures/_static/... equivalents in lectures/pandas_panel.md.
• Updated translation sync state metadata (source SHA, sync date, model, tool version) for pandas_panel.md.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated no comments.

File	Description
lectures/pandas_panel.md	Updates dataset download URLs to reference the non-retired source repository and correct path.
.translate/state/pandas_panel.md.yml	Refreshes translation-sync metadata (source commit, sync timestamp, model/tool versions).
