俄罗斯方块代码python

以下是一个简单的俄罗斯方块游戏的Python代码示例：

# 初始化pygame
pygame.init()

# 定义颜色
BLACK = (0, 0, 0)

RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

# 设置屏幕大小
SCREEN_WIDTH = 400
SCREEN_HEIGHT = 500
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

# 设置游戏标题
pygame.display.set_caption("Tetris")

# 定义方块大小
BLOCK_SIZE = 20

# 定义方块类型和颜色
