python拼图小游戏代码

下面是一个基于Python的拼图小游戏代码示例：

import random

# 定义一个常量表示空白拼图的位置
BLANK = 0

# 初始化拼图游戏
def init_game(size):
    game_board = [[size * i + j + 1 for j in range(size)] for i in range(size)]
    game_board[size - 1][size - 1] = BLANK
    return game_board

# 随机打乱拼图
def shuffle_board(game_board):
    size = len(game_board)
    moves = ['up', 'down', 'left', 'right']
    for _ in range(size * size * 100):
        valid_moves = get_valid_moves(game_board)
        random_move = random.choice(valid_moves)
        make_move(game_board, random_move)

# 打印拼图
def print_board(game_board):
    size = len(game_board)
    for i in range(size):
        for j in range(size):
            if game_board[i][j] == BLANK:
                print('   ', end='')
            else:
                print(f' {game_board[i][j]:2} ', end='')
        print()

# 获取当前合法的拼图移动方向
def get_valid_moves(game_board):
    size = len(game_board)
    blank_pos = find_blank(game_board)
    valid_moves = []
    if blank_pos[0] > 0:
        valid_moves.append('up')
    if blank_pos[0] < size - 1:
        valid_moves.append('down')
    if blank_pos[1] > 0:
        valid_moves.append('left')
    if blank_pos[1] < size - 1:
        valid_moves.append('right')
    return valid_moves

# 根据移动方向改变拼图状态
def make_move(game_board, direction):
    blank_pos = find_blank(game_board)
    if direction == 'up':
        swap(game_board, blank_pos, (blank_pos[0] - 1, blank_pos[1]))
    elif direction == 'down':
        swap(game_board, blank_pos, (blank_pos[0] + 1, blank_pos[1]))
    elif direction == 'left':
        swap(game_board, blank_pos, (blank_pos[0], blank_pos[1] - 1))
    elif direction == 'right':
        swap(game_board, blank_pos, (blank_pos[0], blank_pos[1] + 1))

# 交换两个位置的拼图块
def swap(game_board, pos1, pos2):
    game_board[pos1[0]][pos1[1]], game_board[pos2[0]][pos2[1]] = game_board[pos2[0]][pos2[1]], game_board[pos1[0]][pos1[1]]

# 找到空白拼图的位置
def find_blank(game_board):
    size = len(game_board)
    for i in range(size):
        for j in range(size):
            if game_board[i][j] == BLANK:
                return (i, j)

# 检查是否完成拼图
def is_complete(game_board):
    size = len(game_board)
    for i in range(size):
        for j in range(size):
            if game_board[i][j] != size * i + j + 1:
                return False
    return True

# 游戏主循环
def main():
    size = int(input("请输入拼图大小："))
    game_board = init_game(size)
    shuffle_board(game_board)
    while True:
        print_board(game_board)
        if is_complete(game_board):
            print("恭喜你完成拼图！")
            break
        valid_moves = get_valid_moves(game_board)
        move = input(f"可供选择的移动方向：{valid_moves}，请输入移动方向：")
        if move not in valid_moves:
            print("错误移动！")
            continue
        make_move(game_board, move)

# 启动游戏
if __name__ == "__main__":
    main()

这个程序实现了一个基本的拼图小游戏。你可以根据自己的需要修改和优化代码来实现更丰富的功能，比如增加计时器、计步器以及更美观的界面等。另外，此代码适合在命令行界面下运行。
