Overall	8.9/10

Summary: The 'Merging Dataframes and Filling NaNs' section is translated accurately and fluently, with correct technical terminology and proper MyST/code formatting preserved. Minor stylistic improvements are possible in a couple of sentences (e.g., the 'on' key explanation and the opening comparison to SQL), but these do not affect comprehension or correctness. No syntax errors were found. Accurate and complete rendering of the merging/joining concepts, including the left/right/inner/outer join explanations Consistent and correct terminology for DataFrame, MultiIndex, NaN, and pandas-specific method names, left unmodified as expected Good adherence to French typography rules (guillemets for 'on', 'NaN', 'Country', etc., and non-breaking spaces before high punctuation) Natural French phrasing throughout the merging section, avoiding calques while preserving technical precision

Suggestions:

• [minor · terminology] lectures/pandas_panel.md — ## Fusion de dataframes et remplissage des NaN — "qui sera la key utilisée pour fusionner les dataframes (« on »).": The restructuring of 'the key that is used to merge the dataframes 'on'' into 'qui sera la key utilisée pour fusionner les dataframes (« on »)' is a reasonable adaptation, but it slightly obscures that 'on' refers to the merge parameter. The parenthetical placement is a bit awkward in French and could be clearer. → qui sera la key sur laquelle (« on ») les dataframes seront fusionnés.
• [minor · accuracy] lectures/pandas_panel.md — ## Fusion de dataframes et remplissage des NaN — "nous ajouterons le continent de chaque pays à realwage_f avec la fonction merge": Minor stylistic point: 'Similairement aux bases de données relationnelles' is a slightly calqued construction from English 'Similar to'; more natural French would use 'À l'instar des bases de données relationnelles' or 'Comme pour les bases de données relationnelles'. → Comme pour les bases de données relationnelles telles que SQL, pandas dispose de méthodes intégrées pour fusionner des ensembles de données.
• [nit · terminology] lectures/pandas_panel.md — ## Fusion de dataframes et remplissage des NaN — jointure descriptions: The terms 'left join', 'right join', 'outer join', 'inner join' are kept in English with lowercase French descriptors ('la jointure left'), which is acceptable and common practice in French technical writing, but could optionally be italicized or marked as English terms for clarity (e.g. left join).

What changed in this PR

This PR is an automated translation sync from the upstream English repository (QuantEcon/lecture-python-programming PR #645). It corrects the French prose describing the .replace() operation in the pandas_panel lecture, so the text accurately reflects that a single .replace() call with a list is used rather than a loop.

Changes:

• Updated the French sentence to describe .replace() being used "avec une liste" (with a list) instead of "et boucler sur" (and looping over), matching the actual code behavior.
• Updated the translation state metadata (source-sha, synced-at, tool-version).

File	Description
lectures/​pandas_panel.md	Corrects the prose to accurately describe the single .replace() call with a list rather than a loop.
.translate/​state/​pandas_panel.md.yml	Routine metadata update (source SHA, sync date, tool version) for the translation sync.
