用python给个俄罗斯方块

抱歉，作为AI语言模型，我无法提供可视化的游戏程序。不过，以下是Python实现俄罗斯方块游戏的示例代码供您参考：

import pygame
import random

# 定义常量
WIDTH, HEIGHT = 640, 480
BLOCK_SIZE = 20
ROWS = HEIGHT // BLOCK_SIZE
COLS = WIDTH // BLOCK_SIZE

# 定义方块类型
I_BLOCK = [[1, 1, 1, 1]]
J_BLOCK = [[1, 0, 0], [1, 1, 1]]
L_BLOCK = [[0, 0, 1], [1, 1, 1]]
O_BLOCK = [[1, 1], [1, 1]]
S_BLOCK = [[0, 1, 1], [1, 1, 0]]
T_BLOCK = [[0, 1, 0], [1, 1, 1]]
Z_BLOCK = [[1, 1, 0], [0, 1, 1]]
BLOCK_TYPES = [I_BLOCK, J_BLOCK, L_BLOCK, O_BLOCK, S_BLOCK, T_BLOCK, Z_BLOCK]

# 初始化pygame
pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT))
clock = pygame.time.Clock()

# 定义函数：绘制方块
def draw_block(x, y, color):
    rect = pygame.Rect(x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE)
    pygame.draw.rect(screen, color, rect)

# 定义类：俄罗斯方块
class Tetromino:
    def __init__(self, x, y, shape):
        self.x = x
        self.y = y
        self.shape = shape
        self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
        self.rotation = 0
        
    def rotate(self):
        self.rotation = (self.rotation + 1) % 4
        self.shape = self.get_rotated_shape()
        
    def get_rotated_shape(self):
        return [[self.shape[y][x] for y in range(len(self.shape))] for x in range(len(self.shape[0])-1, -1, -1)]
        
    def draw(self):
        for y, row in enumerate(self.shape):
            for x, col in enumerate(row):
                if col == 1:
                    draw_block(self.x + x, self.y + y, self.color)
    
    def move_down(self):
        self.y += 1
        
    def move_left(self):
        self.x -= 1
        
    def move_right(self):
        self.x += 1

# 定义类：游戏
class Game:
    def __init__(self):
        self.board = [[0 for x in range(COLS)] for y in range(ROWS)]
        self.tetromino = Tetromino(COLS // 2 - 2, 0, random.choice(BLOCK_TYPES))
        self.score = 0
        
    def draw_board(self):
        for y, row in enumerate(self.board):
            for x, col in enumerate(row):
                if col != 0:
                    draw_block(x, y, (255, 255, 255))
        
    def check_collision(self, x, y, shape):
        for y, row in enumerate(shape):
            for x, col in enumerate(row):
                if col == 1:
                    if y + self.tetromino.y >= ROWS or x + self.tetromino.x < 0 or x + self.tetromino.x >= COLS or self.board[y + self.tetromino.y][x + self.tetromino.x] != 0:
                        return True
        return False
    
    def merge_tetromino(self):

            for x, col in enumerate(row):
                if col == 1:
                    self.board[y + self.tetromino.y][x + self.tetromino.x] = self.tetromino.color[0]
        self.tetromino = Tetromino(COLS // 2 - 2, 0, random.choice(BLOCK_TYPES))
        
    def check_lines(self):
        lines_to_remove = []
        for y, row in enumerate(self.board):
            if 0 not in row:
                lines_to_remove.append(y)
        for y in lines_to_remove:
            self.board = [[0 for x in range(COLS)]] + self.board[:y] + self.board[y+1:]
        self.score += len(lines_to_remove) ** 2
        
    def draw(self):
        screen.fill((0, 0, 0))
        self.draw_board()
        self.tetromino.draw()
        pygame.display.update()
    
    def run(self):
        while True:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    return
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        pygame.quit()
                        return
                    if event.key == pygame.K_SPACE:
                        self.tetromino.rotate()
                    if event.key == pygame.K_LEFT:
                        self.tetromino.move_left()
                    if event.key == pygame.K_RIGHT:
                        self.tetromino.move_right()
            if self.check_collision(self.tetromino.x, self.tetromino.y+1, self.tetromino.shape):
                self.merge_tetromino()
                self.check_lines()
            else:
                self.tetromino.move_down()
            self.draw()
            clock.tick(10)

# 启动游戏
game = Game()
game.run()

该示例代码使用了pygame库来实现可视化效果，并实现了俄罗斯方块的基本逻辑，包括方块的旋转、移动、合并、消除等操作。您可以根据需要自行调整代码来增加游戏的难度、功能等。
