Question

我想创建扫雷，所以制作此代码

def mines(m,n):
    matrix = [[ '*' for m in range(10)] for n in range(10)]
    for sublist in matrix:
        s = str(sublist)
        s = s.replace('[', '|').replace(']', '|').replace(',', "")
        print(s)

并创建一个网格10x10，看起来像：

| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * | * |

现在我想要随机定位一个＆＃39; O＆＃39;我知道我必须随机使用，但不知道如何添加

Answer 1

我会这样做，使用random.sample来获取唯一的坐标：

positions = random.sample(range(100), amount_you_want)
for coord in positions:
    matrix[coord%10][coord//10] = 'O'

当然，import random位于顶部。

Answer 2

我会稍微重构你的代码，因为我认为你错过了学习OOP的巨大机会。

class Tile(object):
    """Tile defines an individual square of the board. This is an ABC, don't
instantiate it yourself but use Mine and Empty"""
    shape = "!"
    def __init__(self):
        self.flagged = False
    def __str__(self):
        return "?" if self.flagged else self.shape

class Mine(Tile):
    shape = "O"

class Empty(Tile):
    shape = "."

class MineSweeperBoard(object):
    def __init__(self, size, num_mines):
        self.max_x, self.max_y = size
        self.num_mines = num_mines
        self.field = [[Empty() for y in range(self.max_y)] for x in range(self.max_x)]
        self.generateMines()

    def generateMines(self):
        from random import randrange
        for _ in range(self.num_mines):
            while True:
                x, y = randrange(self.max_x), randrange(self.max_y)
                if not isinstance(self.field[y][x], Mine):
                    self.field[y][x] = Mine()
                    break

    def run(self):
        """Runs the game of minesweeper"""
        # implement your runnable code!

Answer 3

这行代码：

matrix[random.randrange(10)][random.randrange(10)] = 'O' # genrates the bomb***

只运行一次，因此只生成一枚炸弹。要在x和y-1之间生成随机数量的炸弹，请将其包裹在for循环中：

for _ in range(x, y):
    matrix[random.randrange(10)][random.randrange(10)] = 'O' # generates the bomb

如果您需要特定数量的炸弹，请注意这可以创建重叠炸弹（同一坐标不止一次） - 如果这是一个问题，您可以切换到while循环，直到生成正确的数字

设置在随机位置
