用python编辑一个俄罗斯方块游戏

可以使用 Pygame 库来编写俄罗斯方块游戏的 Python 版本。以下是一个基本的俄罗斯方块游戏代码的示例：

import pygame
import random

pygame.init()

# 游戏区宽度和高度
SCREEN_WIDTH = 400
SCREEN_HEIGHT = 600

# 方块的大小
BLOCK_SIZE = 20

# 游戏区列数和行数
NUM_COLUMNS = SCREEN_WIDTH // BLOCK_SIZE
NUM_ROWS = SCREEN_HEIGHT // BLOCK_SIZE

# 方块类型和颜色
BLOCK_TYPES = ['I', 'J', 'L', 'O', 'S', 'T', 'Z']
BLOCK_COLORS = {
    'I': (0, 255, 255),  # 青色
    'J': (0, 0, 255),  # 蓝色
    'L': (255, 165, 0),  # 橙色
    'O': (255, 255, 0),  # 黄色
    'S': (0, 255, 0),  # 绿色
    'T': (128, 0, 128),  # 紫色
    'Z': (255, 0, 0)  # 红色
}

# 定义方块类
class Block():
    def __init__(self, type, x, y):
        self.type = type
        self.color = BLOCK_COLORS[type]
        self.x = x

    def draw(self, screen):
        pygame.draw.rect(screen, self.color, [self.x * BLOCK_SIZE, self.y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE])
