Python pour la data science

Lino Galiana

doi:10.5281/zenodo.8229676

Les parties précédentes étaient très tournées sur l’acquisition de compétences minimales dans chaque domaine de l’analyse de données. Cette partie propose des éléments plus avancés mais plus représentatifs du travail quotidien du data scientist. Cette partie présente la manière dont Python peut être utilisé dans une architecture moderne de type cloud. Elle illustre la manière dont Python peut servir de couteau-suisse faisant l’interface entre différents langages plus efficaces ou plusieurs types de données.

Cette partie est en cours de construction et présentera les éléments suivants :
