写一个俄罗斯方块的python代码

好的，我可以回答这个问题。以下是一个简单的俄罗斯方块的Python代码：

import pygame
import random

# 游戏界面的大小
WINDOW_WIDTH = 400
WINDOW_HEIGHT = 600

# 方块的大小
BLOCK_SIZE = 20

# 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), (255, 255, 255)]

# 俄罗斯方块的形状
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]],
    [[7, 7, 7, 7]]
]

# 初始化pygame
pygame.init()

# 创建游戏界面
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))

# 设置游戏标题
pygame.display.set_caption("俄罗斯方块")

# 创建字体对象
font = pygame.font.SysFont(None, 36)

# 创建方块类
class Block:
    def __init__(self, shape, color):
        self.shape = shape
        self.color = color
        self.x = 4
        self.y = 0

    # 旋转方块
    def rotate(self):
        self.shape = [[self.shape[j][i] for j in range(len(self.shape))] for i in range(len(self.shape[0])-1, -1, -1)]

    # 判断方块是否可以移动
    def can_move(self, dx, dy, board):
        for i in range(len(self.shape)):
            for j in range(len(self.shape[0])):
                if self.shape[i][j] != 0:
                    x = self.x + j + dx
                    y = self.y + i + dy
                    if x < 0 or x >= 10 or y < 0 or y >= 20 or board[y][x] != 0:
                        return False
        return True

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

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

# 创建游戏类

    # 判断是否可以消除一行
    def can_clear(self, y):

                return False
        return True

    # 消除一行
    def clear(self, y):

        score_text = font.render("Score: "+str(self.score), True, COLORS[7])

                    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)

# 创建游戏对象并运行游戏

希望这个代码对你有所帮助！
