帮我写一个扫雷的代码

好的，我会写一个扫雷的代码给您。请注意，这仅是一个基本的代码实现，可以供您参考：

class MineField:
    def __init__(self, row, col, mines):
        self.row = row
        self.col = col
        self.mines = mines
        self.field = [[0] * col for _ in range(row)]
        self.state = [[False] * col for _ in range(row)]
        self.generate_mines()
        self.calculate_mines()

    def generate_mines(self):
        mines = self.mines
        while mines:
            x = random.randint(0, self.row-1)
            y = random.randint(0, self.col-1)
            if self.field[x][y] == 0:
                self.field[x][y] = -1
                mines -= 1

    def calculate_mines(self):
        for i in range(self.row):
            for j in range(self.col):
                if self.field[i][j] == -1:
                    continue
                count = 0
                for x, y in [(i-1, j-1), (i-1, j), (i-1, j+1),
                             (i, j-1), (i, j+1),
                             (i+1, j-1), (i+1, j), (i+1, j+1)]:
                    if 0 <= x < self.row and 0 <= y < self.col and self.field[x][y] == -1:
                        count += 1
                self.field[i][j] = count

    def dfs(self, x, y):
        if x < 0 or x >= self.row or y < 0 or y >= self.col:
            return
        if self.field[x][y] == -1 or self.state[x][y]:
            return
        self.state[x][y] = True
        if self.field[x][y] == 0:
            for i, j in [(x-1, y-1), (x-1, y), (x-1, y+1),
                         (x, y-1), (x, y+1),
                         (x+1, y-1), (x+1, y), (x+1, y+1)]:
                self.dfs(i, j)

    def show(self):
        print('-' * (2 * self.col + 1))
        for i in range(self.row):
            line = '|'
            for j in range(self.col):
                if self.state[i][j]:
                    line += ' ' if self.field[i][j] == 0 else str(self.field[i][j])
                else:
                    line += '*'
                line += '|'
            print(line)
            print('-' * (2 * self.col + 1))
