用python写俄罗斯方块的游戏，100行代码

以下是一个简单的俄罗斯方块游戏，只需要100行代码就可以实现。请注意，这个游戏还有很多地方可以优化和改进，但是它可以作为一个入门级别的示例。

import pygame

pygame.init()

# 游戏区域的宽度和高度，以方块大小为单位
play_width = 10 * block_size  # 10个方块宽
play_height = 20 * block_size  # 20个方块高

# 游戏区域的位置
play_x = (window_width - play_width) // 2
play_y = window_height - play_height - 20

# 定义方块的形状和颜色
shapes = [
    (255, 0, 0, [(0, 0), (1, 0), (2, 0), (3, 0)]),  # I

这个游戏使用了 Pygame 库来实现图形界面和游戏循环。在游戏循环中，我们首先处理事件，然后移动方块并检查是否可以合法移动。如果方块不能继续下落，则锁定方块并清除行。最后，我们绘制游戏界面并检查游戏是否结束。
