polars is a modern library for data analysis ("dataframes for the new era")

We need to add a lecture to cover this topic and introduce this package

  • copy the current pandas lecture and rewrite the lecture using polars
  • reorganise the lecture series to include a section on "Working with Data"

    Delivered by #408, merged 2026-07-30, which adds lectures/polars.md modeled on the existing pandas lecture.

    Both checklist items are complete. The pandas lecture was rewritten using Polars, and lectures/_toc.yml now carries a "Working with Data" part containing pandas, pandas_panel and polars — the reorganisation landed on main independently of the PR.

    Closing as completed. One follow-up defect found while validating the translation sync is tracked separately in #589.
