#### Union { #union }

Vous pouvez déclarer qu'une variable peut être **plusieurs types**, par exemple, un `int` ou un `str`.

Pour le définir, vous utilisez la <dfn title='aussi appelé « opérateur OU bit à bit », mais ce sens n’est pas pertinent ici'>barre verticale (`|`)</dfn> pour séparer les deux types.

C'est ce qu'on appelle une « union », car la variable peut être n'importe quoi dans l'union de ces deux ensembles de types.
