帮我用python做一个俄罗斯方块小游戏

当然可以，不过这个任务比较复杂，需要一定的编程基础和时间，需要你自己动手实现。以下是一个简单的俄罗斯方块小游戏的代码，你可以参考一下：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 360
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("俄罗斯方块")

# 定义方块大小和颜色
block_size = 30
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)
yellow = (255, 255, 0)
purple = (128, 0, 128)
colors = [red, green, blue, yellow, purple]

# 定义方块类型和形状
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]]
]

# 定义游戏区域和边界
play_width = 10 * block_size
play_height = 20 * block_size
play_x = (screen_width - play_width) // 2
play_y = screen_height - play_height - 20
top_left_x = play_x
top_left_y = play_y - 5 * block_size

# 定义方块类
class Block:
    def __init__(self, shape):
        self.shape = shape
        self.color = random.choice(colors)
        self.x = top_left_x + play_width // 2 - len(shape[0]) // 2
        self.y = top_left_y - len(shape)
        self.rotation = 0

    def draw(self):
        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, self.color, (self.x + j * block_size, self.y + i * block_size, block_size, block_size), 0)

    def move(self, dx, dy):
        self.x += dx * block_size
        self.y += dy * block_size

    def rotate(self):
        self.rotation = (self.rotation + 1) % len(self.shape)
        self.shape = rotate_matrix(self.shape)

# 旋转矩阵
def rotate_matrix(matrix):
    return [[matrix[j][i] for j in range(len(matrix))] for i in range(len(matrix[0]) - 1, -1, -1)]

# 检查方块是否合法
def is_valid_pos(block, board):
    for i in range(len(block.shape)):
        for j in range(len(block.shape[0])):
            if block.shape[i][j] != 0:
                x = block.x + j
                y = block.y + i
                if x < 0 or x >= play_width // block_size or y < 0 or y >= play_height // block_size or board[y][x] != 0:
                    return False
    return True

# 将方块加入到游戏区域
def add_block_to_board(block, board):

                y = block.y + i
                board[y][x] = block.color

# 消除满行

            board.insert(0, [0] * (play_width // block_size))
            lines_cleared += 1
    return lines_cleared

# 绘制游戏区域和方块
def draw_play_area(board, score):
    font = pygame.font.SysFont(None, 25)
    label = font.render("Score: " + str(score), True, white)

# 运行游戏
if __name__ == '__main__':
    main()

代码中使用了pygame库来实现游戏界面和操作，具体的实现细节可以自行查阅pygame文档。
