尝试使用Tkinter在python中创建游戏扫雷器，但在查找瓷砖周围的邻居数量时遇到问题

import tkinter as tk

# 创建游戏界面
root = tk.Tk()
root.title("扫雷游戏")

# 生成扫雷棋盘
board = [[0, 0, 0, 1],
         [1, 1, 0, 1],
         [0, 0, 0, 0],
         [1, 0, 1, 1]]

# 处理按钮点击事件
def button_click(row, col):
    # 查找邻居数量
    count = 0
    for i in range(max(0, row-1), min(row+2, len(board))):
        for j in range(max(0, col-1), min(col+2, len(board[0]))):
            if board[i][j] == 1:
                count += 1
    
    # 更新按钮显示
    button = buttons[row][col]
    button.configure(text=str(count))

# 创建按钮
buttons = []
for row in range(len(board)):
    button_row = []
    for col in range(len(board[0])):
        button = tk.Button(root, text="", width=5, height=2, command=lambda r=row, c=col: button_click(r, c))
        button.grid(row=row, column=col)
        button_row.append(button)
    buttons.append(button_row)

root.mainloop()
