俄罗斯方块游戏python代码

好的，以下是一个用 Python 和 Pygame 实现的俄罗斯方块游戏的代码示例。该代码实现了基本的游戏逻辑和图形界面。您可以根据自己的需要进行修改和优化。

import pygame
import random

# 游戏区域宽度和高度
WIDTH = 300
HEIGHT = 600

# 方块大小
BLOCK_SIZE = 30

# 方块种类和颜色

    [[1, 1, 1],
     [0, 1, 0]],

    [[0, 2, 2],
     [2, 2, 0]],

    [[3, 3, 0],
     [0, 3, 3]],

    [[4, 0, 0],
     [4, 4, 4]],

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

    [[6, 6, 6, 6]],

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