生成一个宫格视图的代码

下面是一个简单的 Python 代码示例，用于生成一个 9x9 的宫格视图。你可以根据需要进行修改和扩展。

def print_grid(grid):
    for i in range(9):
        if i % 3 == 0 and i != 0:
            print("- - - - - - - - - - - -")
        for j in range(9):
            if j % 3 == 0 and j != 0:
                print("|", end=" ")
            print(grid[i][j], end=" ")
        print()

# 示例用法
grid = [
    [5, 3, 0, 0, 7, 0, 0, 0, 0],
    [6, 0, 0, 1, 9, 5, 0, 0, 0],
    [0, 9, 8, 0, 0, 0, 0, 6, 0],
    [8, 0, 0, 0, 6, 0, 0, 0, 3],
    [4, 0, 0, 8, 0, 3, 0, 0, 1],
    [7, 0, 0, 0, 2, 0, 0, 0, 6],
    [0, 6, 0, 0, 0, 0, 2, 8, 0],
    [0, 0, 0, 4, 1, 9, 0, 0, 5],
    [0, 0, 0, 0, 8, 0, 0, 7, 9]
]

print_grid(grid)

这个代码将打印出以下宫格视图：

5 3 0 | 0 7 0 | 0 0 0 
6 0 0 | 1 9 5 | 0 0 0 
0 9 8 | 0 0 0 | 0 6 0 
- - - - - - - - - - - -
8 0 0 | 0 6 0 | 0 0 3 
4 0 0 | 8 0 3 | 0 0 1 
7 0 0 | 0 2 0 | 0 0 6 
- - - - - - - - - - - -
0 6 0 | 0 0 0 | 2 8 0 
0 0 0 | 4 1 9 | 0 0 5 
0 0 0 | 0 8 0 | 0 7 9
