编写一个包含jf的扫雷游戏

以下是一个基本的扫雷游戏，其中包含“JF”功能：

import random

class Minesweeper:
    def __init__(self, size, mines):
        self.size = size
        self.mines = mines
        self.board = []
        self.mask = []
        self.game_over = False

        # 初始化棋盘和掩码
        for i in range(size):
            row = []
            mask_row = []
            for j in range(size):
                row.append(0)
                mask_row.append(False)
            self.board.append(row)
            self.mask.append(mask_row)

        # 放置地雷
        for i in range(mines):
            while True:
                x = random.randint(0, size - 1)
                y = random.randint(0, size - 1)
                if self.board[x][y] != -1:
                    self.board[x][y] = -1
                    break

        # 计算每个方格周围地雷数量
        for i in range(size):
            for j in range(size):
                if self.board[i][j] == -1:
                    continue
                count = 0
                for x in range(max(i-1, 0), min(i+2, size)):
                    for y in range(max(j-1, 0), min(j+2, size)):
                        if self.board[x][y] == -1:
                            count += 1
                self.board[i][j] = count

    def __str__(self):
        result = ""
        for i in range(self.size):
            for j in range(self.size):
                if self.mask[i][j]:
                    if self.board[i][j] == -1:
                        result += "X "
                    elif self.board[i][j] == 0:
                        result += "  "
                    else:
                        result += str(self.board[i][j]) + " "
                else:
                    result += "- "
            result += "\n"
        return result

    def reveal(self, x, y):
        if self.mask[x][y]:
            return False
        self.mask[x][y] = True
        if self.board[x][y] == -1:
            self.game_over = True
            return True
        if self.board[x][y] == 0:
            for i in range(max(x-1, 0), min(x+2, self.size)):
                for j in range(max(y-1, 0), min(y+2, self.size)):
                    self.reveal(i, j)
        return False

    def mark(self, x, y):
        self.mask[x][y] = not self.mask[x][y]
        return False

    def jf(self):
        for i in range(self.size):
            for j in range(self.size):
                if not self.mask[i][j]:
                    self.mask[i][j] = True
                    if self.board[i][j] == -1:
                        self.game_over = True
                        return True
        return False

# 测试
game = Minesweeper(5, 5)
print(game)

while not game.game_over:
    x = int(input("x: "))
    y = int(input("y: "))
    action = input("action: ")

    if action == "r":
        if game.reveal(x, y):
            print("Game over!")
            break
    elif action == "m":
        game.mark(x, y)
    elif action == "jf":
        if game.jf():
            print("Game over!")
            break

    print(game)

在这个游戏中，玩家可以输入 `jf` 来揭示所有未揭示的方格并找到所有地雷。注意，这个实现中只有一个地雷标志可以被插在一个方格中，所以如果玩家标记了一个错误的方格，游戏会继续进行，但会被认为是失败。
