俄罗斯方块的源代码

由于俄罗斯方块是一个经典的游戏，其源代码已经在许多不同的编程语言中被实现。以下是一个基于Python语言的简单俄罗斯方块游戏的示例代码:

import pygame
import random

# 定义方块形状
shapes = [
    [[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]]
]

# 设置方块颜色
colors = [
    (0, 0, 0),
    (255, 0, 0),
    (0, 255, 0),
    (0, 0, 255),
    (255, 255, 0),
    (0, 255, 255),
    (255, 0, 255)
]

这只是一个基于Python语言的简单示例，其他编程语言中的实现方式可能会有所不同。
