俄罗斯方块游戏的Python代码_俄罗斯方块python代码

这是一个简单的俄罗斯方块游戏的Python代码，使用了pygame库。请确保你已经安装了pygame库。如果没有，你可以使用以下命令进行安装：

pip install pygame

然后，你可以使用以下代码来创建一个简单的俄罗斯方块游戏：

import pygame  
import random  
  
# 初始化pygame  
pygame.init()  
  
# 设置屏幕大小和标题  
screen_width = 800  
screen_height = 600  
screen = pygame.display.set_mode((screen_width, screen_height))  
pygame.display.set_caption("俄罗斯方块")  
  
# 设置颜色  
WHITE = (255, 255, 255)  
RED = (255, 0, 0)  
GREEN = (0, 255, 0)  
BLACK = (0, 0, 0)  
  
# 定义方块类
