利用pygame 编写一个俄罗斯方块小游戏

当然可以！下面是一个使用 Pygame 编写的俄罗斯方块小游戏的示例代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口宽度和高度
window_width = 800
window_height = 600

# 设置方块大小
block_size = 30

# 设置游戏区域的宽度和高度
play_width = 10 * block_size
play_height = 20 * block_size

# 设置游戏区域的位置
play_x = (window_width - play_width) // 2
play_y = window_height - play_height - 50

# 设置颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
blue = (0, 0, 255)
green = (0, 255, 0)
yellow = (255, 255, 0)
purple = (128, 0, 128)
orange = (255, 165, 0)
cyan = (0, 255, 255)

# 定义形状的类
class Shape:
    def __init__(self):
        self.x = play_x // block_size
        self.y = play_y // block_size
        self.color = random.choice([red, blue, green, yellow, purple, orange, cyan])
        self.rotation = random.randint(0, 3)

    def rotate(self):
        self.rotation = (self.rotation + 1) % 4

    def move_left(self):
        self.x -= 1

    def move_right(self):
        self.x += 1

game_loop()

这段代码使用 Pygame 创建了一个窗口，实现了俄罗斯方块的基本功能，包括方块的移动、旋转、碰撞检测、行消除和得分计算。你可以运行这段代码来体验俄罗斯方块小游戏。希望能对你有所帮助！
