Ok ! I give up ! There is definetly something wrong with my code but I can't figure it out since the output on the console looks fine.
plateau =  for i in range(5): plateau.append(["O"]*5) def afficher_plateau(plateau): for ligne in plateau : print " ".join(ligne) print afficher_plateau(plateau)
On the console I get 5 beautiful rows of 5 "O"s each, but i get this
"oops, try again. it seems you're not printing the right number of elements."
Replace this line with your code.
