用python写个扫雷

好的，这是一个简单的扫雷代码：

import random

class MineSweeper:
    def __init__(self, row, col, mines):
        self.row = row
        self.col = col
        self.mines = mines
        self.board = [[0 for j in range(col)] for i in range(row)]
        self.mines_pos = []
        self.visited = [[False for j in range(col)] for i in range(row)]
    
    def place_mines(self):
        mines_placed = 0
        while mines_placed < self.mines:
            x = random.randint(0, self.row-1)
            y = random.randint(0, self.col-1)
            if [x, y] not in self.mines_pos:
                self.mines_pos.append([x, y])
                mines_placed += 1
    
    def get_adjacent(self, x, y):
        adj = []
        if x > 0:
            adj.append([x-1, y])
        if x < self.row-1:
            adj.append([x+1, y])
        if y > 0:
            adj.append([x, y-1])
        if y < self.col-1:
            adj.append([x, y+1])
        if x > 0 and y > 0:
            adj.append([x-1, y-1])
        if x > 0 and y < self.col-1:
            adj.append([x-1, y+1])
        if x < self.row-1 and y > 0:
            adj.append([x+1, y-1])
        if x < self.row-1 and y < self.col-1:
            adj.append([x+1, y+1])
        return adj
    
    def place_numbers(self):
        for pos in self.mines_pos:
            x, y = pos
            adj = self.get_adjacent(x, y)
            for a in adj:
                a_x, a_y = a
                self.board[a_x][a_y] += 1
    
    def dfs(self, x, y):
        if self.board[x][y] == 0:
            self.visited[x][y] = True
            adj = self.get_adjacent(x, y)
            for a in adj:
                a_x, a_y = a
                if not self.visited[a_x][a_y]:
                    self.dfs(a_x, a_y)
    
    def play(self, x, y):
        if [x, y] in self.mines_pos:
            print("Game Over")
            return False
        else:
            self.dfs(x, y)
            return True
    
    def print_board(self):
        for row in self.board:
            print(row)

game = MineSweeper(5, 5, 5)
game.place_mines()
game.place_numbers()
