列表对象发生检查器python

Question

我正在研究一个小项目，并且在编程中遇到了一些小错误。这是一个基本的战列舰游戏，到目前为止，我有两个“舰船”的设置，并且当我的侧面或敌人侧都被击中时，我的游戏就结束了。

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) 

所以这就是我的列表的基础，但后来在代码中是它给我一点麻烦。

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

有人能帮助我吗？帮助将不胜感激。

更新 对不起，我对我的意思有点不清楚。

我正在使用python 3，如果这有什么区别。所以如果玩家在网格上击中正确的位置，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那些“H”用来结束IF循环。再次感谢，并为此感到抱歉。

你还没有真正解释过这个问题，因此很多代码缺失，很难告诉你什么是错误的，但是我会猜测它。

我的猜测是你创建了一个'='网格来表示一个玩家的棋盘，然后如果他们的船被'命中'，你用'H'代替那个位置上的'='。

创建（enemy_grid）的结构似乎看起来是这样的：

在这种情况下

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

测试，enemy_grid.count("H")没有任何意义，因为enemy_grid是包含其他列表的列表（这样的数Hs总是0--他们在第二层列表中更深）。

你可能想沿着线测试更多：

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