提升 pandas 80% 效率秘訣大公開張憲騰BlockedUnblockFollowFollowingApr 18在上一篇文章:用記憶體講解 python list 為何比較慢我們知道了記憶體的觀念,也解釋了為何大量的數字運算盡量使用 numpy。但 numpy 也不見得那麼好用,且 python 的優勢無法在這個套件內體現,因此,偉大的工程師們寫出了一個基於 numpy 建構,又可以擁有好的資料處理特性的套件 — pandas。此時這已經解決我們大部分的效能問題,只是如果又遇到更大的資料,我們可以如何優化 Pandas呢?這邊你會看到Pandas 是如何運用 Numpy 提高效能的我們還能運用什麼方式幫助 Pandas 讓他跑得更快(如果不想看方法論可以直接滑到底看結論)ps.…
