基本巢循环看起来像这样不工作。但是，我在我的一款游戏中为关卡设计运行了完全相同的事情，并在第一行之后停止。For循环如预期
for row in level:
for col in row:
print col
if col == "G":
g = Grass(x,y)
obsticles.append(g)
entities.add(g)
print "grass added to entites"
elif col == "P":
p = Plain_Grass(x,y)
obsticles.append(p)
entities.add(p)
elif col == "F":
f = Grass_Flower(x,y)
obsticles.append(f)
entities.add(f)
elif col == "Y":
y = Grass_To_SandD(x,y)
obsticles.append(y)
entities.add(y)
我真的不明白为什么。我知道这可能是我所问过的最新鲜的问题，但它真的让我烦恼。我已经尝试完全相同的test和一切。我已经创建了另一个程序，以查看它是否在游戏程序中不起作用，并且确实如此。任何人都可以看到问题吗？
[编辑]这里是我的tilemap的文件：

#This is where all the testing happens...
tilemap = [

也许只有一行？ – Dahaka
你可以显示'level'的值吗？ – Louis
代码中的任何'break'语句？目前我看不到任何理由，所以我想你必须告诉我们更多。 – Alfe
