Summary: The translation of the modified sections in both pandas.md and polars.md is highly accurate, fluent, and terminologically consistent with the provided glossary and French typographic rules. No blocking or major issues were found; only a few minor stylistic and consistency nits remain, primarily around table syntax whitespace and code-comment localization consistency. Excellent, idiomatic French rendering of technical Pandas/Polars vocabulary (e.g., 'évaluation paresseuse', 'descente des prédicats', 'centrée réduite' concepts correctly avoided/adapted where not applicable) with strong consistency across both files French typographic conventions (non-breaking spaces before ; : ! ?, guillemets where applicable) are correctly applied throughout the changed sections Long English sentences are frequently and skillfully split into more natural French sentence structures without losing technical precision Code blocks, LaTeX, and MyST directive syntax are fully preserved with no structural breakage

Suggestions:

• [minor · terminology] lectures/pandas.md — Table headers under DataFrames section: Table alignment markers were altered from :-: to :- : (with an inserted space), which is unnecessary and inconsistent with standard Markdown table syntax, though it does not break rendering in most parsers. → Use :-: instead of :- : for table column alignment markers.
• [minor · fluency] lectures/polars.md — ### Performance comparison, 'Sur quelques lignes, la différence de vitesse est négligeable': The phrase "utilisez celle des API que vous trouvez la plus pratique" is a slightly awkward rendering of "use whichever API you find more convenient"; the split across the code fence makes the sentence read oddly. → "utilisez celle des deux API qui vous convient le mieux."
• [minor · fluency] lectures/polars.md — ### Eager vs lazy, comment '# Rechargement du jeu de données': The code comment was localized, which is acceptable, but note that other code comments in the same file (e.g., in read_data_polars docstring) were left in English, creating inconsistency in whether comments are translated throughout the Polars lecture. → Apply a consistent policy: either translate all code comments/docstrings in changed sections or leave all as-is.
• [nit · terminology] lectures/pandas.md — ## Overview / ## Vue d'ensemble: "munging" is translated as "traitement général des données" in the body text but the footnote uses "munging" transliterated as « munging » in quotes — consistent handling is good, but the in-body translation choice (traitement général vs. nettoyage) differs slightly from the footnote's "nettoyage", which is a minor internal inconsistency. → Consider aligning terms between body text and footnote (e.g., both using "nettoyage/traitement des données").

Pull request overview

This automated translation-sync PR updates the French pandas and polars lecture content to load the test_pwt.csv Penn World Tables sample dataset from the central QuantEcon/data-lectures repository, aligning with upstream source PR #612.

Changes:

• Adjusted the pandas lecture text to refer to test_pwt.csv (instead of the previous pandas/data/test_pwt.csv path).
• Updated translation sync state files to the new upstream source-sha.
