帮我写一个python代码的俄罗斯方块

抱歉，作为AI语言模型，我无法编写和执行代码。但是，我可以提供一个基本的俄罗斯方块游戏实现，其中包括游戏板、方块、移动和旋转等功能。

import pygame
import random

# 游戏板大小
board_width = 10
board_height = 20
# 方块大小
block_size = 30

# 方块形状
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]],

    [[7, 7, 7, 7]]
]

# 方块颜色
colors = [
    (0, 0, 0),
    (255, 0, 0),
    (0, 255, 0),
    (0, 0, 255),
    (255, 255, 0),
    (255, 0, 255),
    (0, 255, 255),
    (128, 128, 128)
]

# 游戏板类
class Board:
    def __init__(self):
        self.board = [[0] * board_width for _ in range(board_height)]

    # 判断是否可以放置方块
    def is_valid(self, shape, x, y):
        for i in range(len(shape)):
            for j in range(len(shape[i])):
                if shape[i][j] != 0:
                    if y + i < 0 or x + j < 0 or y + i >= board_height or x + j >= board_width or self.board[y + i][x + j] != 0:
                        return False
        return True

    # 放置方块
    def place_block(self, shape, x, y, color):
        for i in range(len(shape)):
            for j in range(len(shape[i])):
                if shape[i][j] != 0:
                    self.board[y + i][x + j] = color

    # 消除已满行
    def clear_rows(self):
        rows_cleared = 0
        for i in range(board_height):
            if all(self.board[i]):
                self.board.pop(i)
                self.board.insert(0, [0] * board_width)
                rows_cleared += 1
        return rows_cleared

    # 判断游戏是否结束
    def is_game_over(self):
        return any(self.board[0])

# 方块类
class Block:
    def __init__(self):
        self.shape = random.choice(shapes)
        self.color = random.randint(1, len(colors) - 1)
        self.x = board_width // 2 - len(self.shape[0]) // 2
        self.y = -len(self.shape)

    # 移动方块
    def move(self, dx, dy, board):
        if board.is_valid(self.shape, self.x + dx, self.y + dy):
            self.x += dx
            self.y += dy
            return True
        return False

    # 旋转方块
    def rotate(self, board):
        new_shape = []
        for i in range(len(self.shape[0])):
            row = []
            for j in range(len(self.shape)):
                row.append(self.shape[len(self.shape) - j - 1][i])
            new_shape.append(row)
        if board.is_valid(new_shape, self.x, self.y):
            self.shape = new_shape
            return True
        return False

# 游戏类
class Game:
    def __init__(self):
        pygame.init()
        self.screen = pygame.display.set_mode((board_width * block_size, board_height * block_size))
        pygame.display.set_caption('俄罗斯方块')
        self.clock = pygame.time.Clock()

        # 初始化游戏板和方块
        self.board = Board()
        self.block = Block()

    # 绘制游戏板
    def draw_board(self):
        for i in range(board_height):
            for j in range(board_width):
                pygame.draw.rect(self.screen, colors[self.board.board[i][j]], (j * block_size, i * block_size, block_size, block_size), 0)

    # 绘制方块
    def draw_block(self):
        for i in range(len(self.block.shape)):
            for j in range(len(self.block.shape[i])):
                if self.block.shape[i][j] != 0:
                    pygame.draw.rect(self.screen, colors[self.block.color], ((self.block.x + j) * block_size, (self.block.y + i) * block_size, block_size, block_size), 0)

    # 运行游戏
    def run(self):
        while True:
            # 处理事件
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    exit()
                elif event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_LEFT:
                        self.block.move(-1, 0, self.board)
                    elif event.key == pygame.K_RIGHT:
                        self.block.move(1, 0, self.board)
                    elif event.key == pygame.K_DOWN:
                        self.block.move(0, 1, self.board)
                    elif event.key == pygame.K_UP:
                        self.block.rotate(self.board)

            # 移动方块
            if not self.block.move(0, 1, self.board):
                self.board.place_block(self.block.shape, self.block.x, self.block.y, self.block.color)
                rows_cleared = self.board.clear_rows()
                if rows_cleared > 0:
                    score += rows_cleared * 10
                self.block = Block()

                # 判断游戏是否结束
                if self.board.is_game_over():
                    pygame.quit()
                    exit()

            # 绘制游戏界面
            self.screen.fill((255, 255, 255))
            self.draw_board()
            self.draw_block()
            pygame.display.update()

            # 控制游戏速度
            self.clock.tick(30)

# 运行游戏
if __name__ == '__main__':
    game = Game()
    game.run()

这个实现可能不是最优的，但可以作为一个基本的参考。
