python写个俄罗斯方块游戏

好的，下面是一个简单的俄罗斯方块游戏的Python实现：

import pygame
import random

# 初始化Pygame
pygame.init()

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
CYAN = (0, 255, 255)
MAGENTA = (255, 0, 255)
YELLOW = (255, 255, 0)

# 游戏区域大小
SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480

# 方块大小
BLOCK_SIZE = 20

# 方块类型定义
BLOCK_TYPES = [
    [
        [1, 1, 1],
        [0, 1, 0],
    ],
    [

        [2, 2],

        [0, 0, 5],
        [5, 5, 5],
    ],

        [0, 7, 7],
        [7, 7, 0],
    ],

# 游戏主循环

        # 更新屏幕
        pygame.display.flip()

        # 控制帧率
        clock.tick(10)

# 创建窗口
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

# 运行游戏
main_loop()

# 退出Pygame
pygame.quit()

这个实现并不完整，还可以添加更多的功能和优化。
