      データ分析をpandasを通じて始めたばかりで、実はまだ日が浅いのですが、トレンドが常に変化しているのでpolarsが気になっていました。 pandasと比較してpolarsの長所から始まり、polarsを学ぶ理由から一つ一つ説明してくださるので、授業を受けるモチベーションになりました!また、実習ベースの講義なので、実際のデータを加工してみることができ、興味深く受講できそうです。

          データアナリストを夢見る者として、非常に有益な講義でした。 講義を通して、pandasだけでなく、様々なライブラリを活用することが、より効率的なデータ分析だという考えに至りました。そして、タイタニックデータを利用して探索的データ分析(EDA)を行う過程が一番面白かったです!✨
