Concours de l'Avent 2021 "l'énigme des 3 portes" : jour 4
Posted: 04 Dec 2021, 12:40
Viens rassembler les indices et bouts de code Python chaque jour de l'Avent ; sois parmi les premiers à passer l'une des portes pour gagner de superbes cadeaux de Noël !
Les tiles déjà ou prochainement affichées sont toutes des images converties en Python à l'aide d'img2calc.
