Ils contribuent \u00e9galement \u00e0 la r\u00e9utilisation du code, ce qui signifie qu&#039;un bloc de code peut \u00eatre utilis\u00e9 plusieurs fois dans le programme sans avoir \u00e0 le r\u00e9\u00e9crire \u00e0 chaque fois. Les fonctions Python peuvent \u00eatre appel\u00e9es \u00e0 n&#039;importe quel moment du programme et peuvent \u00e9galement renvoyer des valeurs, ce qui en fait des outils polyvalents pour r\u00e9soudre des probl\u00e8mes de programmation complexes.
