ceci est ma fonction: quand j'exécute, ça me donne la valeur de node mais au lieu de ça, ça me donne une erreur. La valeur de i = 0 dans la fonction d'action d'obtention. Je ne sais pas, pourquoi il n'augmente pas.
while stack.isEmpty()!= 0:
node = stack.pop()
print node
Erreur:
(5, 5)
Path found with total cost of 999999 in 0.0 seconds

None
Ce n'est pas une erreur, c'est juste une sortie normale. – Zaz
