请用python写语言一个俄罗斯方块游戏

好的，我可以给您提供一个简易版的俄罗斯方块游戏代码，您可以在此基础上进行改进和完善。

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 300
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("俄罗斯方块")

# 定义方块大小
block_size = 30

# 定义方块的形状
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]],

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

# 定义方块颜色
colors = [(0, 0, 0),  # 黑色
          (255, 0, 0),  # 红色
          (0, 255, 0),  # 绿色
