用Python写一个数独游戏

好的，以下是一个简单的Python数独游戏代码：

import numpy as np

def print_board(board):
    for i in range(9):
        for j in range(9):
            print(board[i][j], end=" ")
            if j == 2 or j == 5:
                print("|", end=" ")
        print()
        if i == 2 or i == 5:
            print("-" * 21)

def find_empty(board):
    for i in range(9):
        for j in range(9):
            if board[i][j] == 0:
                return (i, j)
    return None

def valid(board, num, pos):
    # Check row
    for i in range(9):
        if board[pos[0]][i] == num and pos[1] != i:
            return False
    # Check column
    for i in range(9):
        if board[i][pos[1]] == num and pos[0] != i:
            return False
    # Check box
    box_x = pos[1] // 3
    box_y = pos[0] // 3
    for i in range(box_y * 3, box_y * 3 + 3):
        for j in range(box_x * 3, box_x * 3 + 3):
            if board[i][j] == num and (i, j) != pos:
                return False
    return True

def solve(board):
    find = find_empty(board)
    if not find:
        return True
    else:
        row, col = find
    for i in range(1, 10):
        if valid(board, i, (row, col)):
            board[row][col] = i
            if solve(board):
                return True
            board[row][col] = 0
    return False

board = np.array([[0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0],
                  [0, 0, 0, 0, 0, 0, 0, 0, 0]])

# Sample board
board[0][2] = 4
board[0][3] = 3
board[0][5] = 2
board[0][7] = 9
board[1][0] = 6
board[1][1] = 7
board[1][4] = 1
board[1][6] = 2
board[2][1] = 4
board[2][2] = 9
board[2][3] = 5
board[2][4] = 8
board[2][5] = 7
board[2][6] = 1
board[3][2] = 5
board[3][3] = 2
board[3][5] = 1
board[3][6] = 8
board[4][0] = 2
board[4][8] = 1
board[5][2] = 7
board[5][3] = 6
board[5][5] = 5
board[5][6] = 3
board[6][1] = 1
board[6][2] = 3
board[6][3] = 4
board[6][4] = 6
board[6][5] = 9
board[6][6] = 7
board[7][2] = 6
board[7][4] = 3
board[7][7] = 5
board[8][1] = 8
board[8][3] = 7
board[8][5] = 4
board[8][6] = 6

print("Original board:")
print_board(board)
print("\nSolved board:")
solve(board)
print_board(board)

这个代码可以生成一个数独游戏，并且可以自动解决它。
