实现俄罗斯方块的python代码

我可以回答这个问题。以下是一个简单的实现俄罗斯方块的Python代码：

import random

# 定义方块的形状
shapes = [
    [[1, 1, 1], [0, 1, 0]],
    [[0, 2, 2], [2, 2, 0]],
    [[3, 3, 0], [0, 3, 3]],
    [[4, 0, 0], [4, 4, 4]],
    [[0, 0, 5], [5, 5, 5]],
    [[6, 6], [6, 6]]
]

# 定义方块的颜色
colors = [
    (0, 0, 0),
    (255, 0, 0),
    (0, 255, 0),
    (0, 0, 255),
    (255, 255, 0),
    (255, 0, 255),
    (0, 255, 255)
]

# 定义游戏区域的大小
board_width = 10
board_height = 20

# 定义游戏区域
board = [[0] * board_width for _ in range(board_height)]

# 定义方块的初始位置
current_shape = random.choice(shapes)
current_color = random.randint(1, len(colors) - 1)
current_x = board_width // 2 - len(current_shape[0]) // 2
current_y = 0

# 定义游戏循环
while True:
    # 绘制游戏区域
    for y in range(board_height):
        for x in range(board_width):
            if board[y][x] == 0:
                pygame.draw.rect(screen, (128, 128, 128), (x * 20, y * 20, 20, 20))
            else:
                pygame.draw.rect(screen, colors[board[y][x]], (x * 20, y * 20, 20, 20))

    # 绘制当前方块
    for y in range(len(current_shape)):
        for x in range(len(current_shape[0])):
            if current_shape[y][x] != 0:
                pygame.draw.rect(screen, colors[current_color], ((current_x + x) * 20, (current_y + y) * 20, 20, 20))

    # 更新屏幕
    pygame.display.update()

    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    # 移动方块
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        if current_x > 0:
            current_x -= 1
    if keys[pygame.K_RIGHT]:
        if current_x < board_width - len(current_shape[0]):
            current_x += 1
    if keys[pygame.K_DOWN]:
        if current_y < board_height - len(current_shape):
            current_y += 1

    # 判断方块是否落地
    if current_y + len(current_shape) == board_height or \
            any(board[current_y + y][current_x + x] != 0 for y in range(len(current_shape)) for x in range(len(current_shape[0]))):
        # 将方块放到游戏区域中
        for y in range(len(current_shape)):
            for x in range(len(current_shape[0])):
                if current_shape[y][x] != 0:
                    board[current_y + y][current_x + x] = current_color
        # 生成新的方块
        current_shape = random.choice(shapes)
        current_color = random.randint(1, len(colors) - 1)
        current_x = board_width // 2 - len(current_shape[0]) // 2
        current_y = 0

    # 消除满行
    for y in range(board_height):
        if all(board[y][x] != 0 for x in range(board_width)):
            for y2 in range(y, 0, -1):
                board[y2] = board[y2 - 1].copy()
            board[0] = [0] * board_width

    # 延迟一段时间
    pygame.time.delay(100)

这段代码使用 Pygame 库实现了一个简单的俄罗斯方块游戏。
