列表对象引用检查器python

我在做一个小项目，在编程中遇到了一个小错误。这是一个基本的战舰游戏，到目前为止，我已经设置了两个“战舰”，当我或敌人双方都被击中时，游戏就结束了

def enemy_board():
global enemy_grid
enemy_grid = []
for i in range (0,10):
    enemy_grid.append(["="] * 10)
def random_row_one(enemy_grid):
    return randint(0, len(enemy_grid) - 1)
def random_col_one(enemy_grid):
    return randint(0, len(enemy_grid) - 1)   
def random_row_two(enemy_grid):
    return randint(0, len(enemy_grid) - 1)
def random_col_two(enemy_grid):
    return randint(0, len(enemy_grid) - 1)
global x_one
x_one = random_row_one(enemy_grid)
global y_one
y_one = random_col_one(enemy_grid)
global x_two
x_two = random_row_two(enemy_grid)
global y_two
y_two = random_col_two(enemy_grid)
print(x_one)
print(y_one)
print(x_two)
print(y_two)

这是我列表的基础，但在代码的后面，它给了我一点麻烦

elif enemy_grid.count("H") == 2:
    print("\nYou got them all!\n")
    break

更新 对不起，我有点不明白我的意思

如果有什么不同的话，我使用的是Python3。因此，如果玩家在网格上点击了正确的位置，那么它将显示为“H”，而不是“=”或“O”。所以我只是想知道我是否可以计算用来结束if循环的那些“H”。

您还没有真正解释这个问题，而且缺少太多的代码，所以很难告诉您出了什么问题，不过我还是要猜测一下

我的猜测是，你创建一个“=”网格来表示玩家的棋盘，然后如果他们的船被“击中”，你就用一个“H”替换该位置的“=”

您创建的结构（敌方网格）看起来像：

[[====]
 [====]
 [====]
 [....]]

在这种情况下，您的测试，

敌方网格。计数（“H”）

没有意义，因为敌方网格是一个包含其他列表的列表（因此Hs的计数将始终为0-它们在列表的第二层更深）

您可能需要一个更符合以下内容的测试：

[cell for row in enemy_grid for cell in row].count('H')

问题是什么？破损的缩进使代码很难理解<代码>全局函数外的声明无效。您不需要用不同的名称定义同一函数四次（

random_u2;（row/col）2;（one/two）

）！只定义一次，然后叫四次。“给我一点麻烦”什么麻烦？请显示完整的错误消息。很抱歉，还有一次更新，为了最小化问题中的空间，我删除了一个定义（title（））。如果是这样的话，很抱歉，谢谢！我只是在重新考虑我的代码，你的建议很正确！很抱歉，我无法更轻松地表达我的问题，但你明白了。我只需要在代码中切换IF语句的位置，根据您的建议，它现在可以完美地工作了！非常感谢。
