Python Web Development Techdegree Graduate 14,822 PointsYou can use list of lists, creating a map or world of a game.
world = []
for item in range(3):
world.append(["O"] * 3)
then you can print your world:
def showworld(world):
for level in world:
print(" ".join(level))
Coordinates are very representative this way.
