Ce qui signifie : "la variable `items` est une `list`, et chacun de ses éléments a pour type `str`.

En faisant cela, votre éditeur pourra vous aider, même pendant que vous traitez des éléments de la liste.

Sans types, c'est presque impossible à réaliser.

Vous remarquerez que la variable `item` n'est qu'un des éléments de la list `items`.
