python数独游戏源代码

以下是一个简单的Python数独游戏源代码：

import random

# 创建数独棋盘
def create_board():
    seed = [1, 2, 3, 4, 5, 6, 7, 8, 9]
    random.shuffle(seed)
    board = [[0]*9 for i in range(9)]
    for i in range(9):
        board[0][i] = seed[i]
    for i in range(1, 9):
        for j in range(9):
            board[i][j] = board[i-1][(j+3)%9]
    return board

# 打印数独棋盘
def print_board(board):
    print("-"*25)
    for i in range(9):
        for j in range(9):
            print(board[i][j], end=" ")
            if j%3 == 2:
                print("|", end=" ")
        print()
        if i%3 == 2:
            print("-"*25)

# 检查行、列、小九宫格是否有重复数字
def check(board, row, col, num):
    for i in range(9):
        if board[row][i] == num:
            return False
    for i in range(9):
        if board[i][col] == num:
            return False
    r = (row//3)*3
    c = (col//3)*3
    for i in range(3):
        for j in range(3):
            if board[r+i][c+j] == num:
                return False
    return True

# 解数独
def solve(board):
    for row in range(9):
        for col in range(9):
            if board[row][col] == 0:
                for num in range(1, 10):
                    if check(board, row, col, num):
                        board[row][col] = num
                        if solve(board):
                            return True
                        board[row][col] = 0
                return False
    return True

# 创建数独棋盘并解决
board = create_board()
print("原始数独：")
print_board(board)
solve(board)
print("解决后的数独：")
print_board(board)

可以通过调用`create_board()`函数创建一个数独棋盘，通过调用`solve()`函数解决数独，最后通过调用`print_board()`函数打印结果。
