Cette partie du site présente un élément qui n’est pas propre à Python mais qui est néanmoins indispensable : la pratique de Git.

Une grande partie du contenu de la partie provient d’un cours dédié fait avec Romain Avouac.

Le chapitre de présentation de Git propose une introduction visant à présenter l’intérêt d’utiliser cet outil. Une mise en pratique est proposée avec un cadavre exquis.

0.1 Utilisation de `Git` avec `Python`

Git est à la fois un outil et un langage. Il est donc nécessaire d’installer, dans un premier temps Git Bash, puis de connecter son outil préféré pour faire du Python (qu’il s’agisse de Jupyter, VSCode ou PyCharm).

Cette partie est structurée en 2 temps :
