就是这么强大，强大到你不敢相信。
下面是一个简单的俄罗斯方块小程序的实现，使用Python和`pygame`库。如果你还没有安装`pygame`，可以通过以下命令安装：
```bash
pip install pygame
```
### 代码实现
```python
import pygame
import random
# 初始化pygame
pygame.init()
# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GRAY = (128, 128, 128)
COLORS = [
(0, 255, 255), # 青色
(255, 255, 0), # 黄色
(255, 165, 0), # 橙色
(0, 0, 255), # 蓝色
(0, 255, 0), # 绿色
(255, 0, 0), # 红色
(128, 0, 128) # 紫色
]
# 定义屏幕大小
SCREEN_WIDTH = 300
SCREEN_HEIGHT = 600
BLOCK_SIZE = 30
# 定义形状
SHAPES = [
[[1, 1, 1, 1]], # I
[[1, 1, 1], [0, 1, 0]], # T
[[1, 1], [1, 1]], # O
[[0, 1, 1], [1, 1, 0]], # S
[[1, 1, 0], [0, 1, 1]], # Z
[[1, 0, 0], [1, 1, 1]], # L
[[0, 0, 1], [1, 1, 1]] # J
]
# 定义游戏区域
class Board:
def __init__(self, width, height):

for i in lines_to_clear:

self.grid.insert(0, [0 for _ in range(self.width)])
# 定义方块

# 主游戏循环

# 绘制游戏区域
for y, row in enumerate(board.grid):
for x, cell in enumerate(row):
if cell:
pygame.draw.rect(screen, cell, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
pygame.draw.rect(screen, GRAY, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE), 1)
# 绘制当前方块
for i, row in enumerate(board.current_piece.shape):
for j, cell in enumerate(row):
if cell:
x = board.current_piece.x + j
y = board.current_piece.y + i
pygame.draw.rect(screen, board.current_piece.color, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
pygame.draw.rect(screen, GRAY, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE), 1)
pygame.display.flip()
pygame.quit()
if __name__ == "__main__":
main()
```
### 运行说明
1. 安装`pygame`库：`pip install pygame`
2. 将上述代码保存为一个Python文件，例如`tetris.py`。
3. 运行该文件：`python tetris.py`。
### 游戏操作
- 左右方向键：移动方块
- 上方向键：旋转方块
- 下方向键：加速方块下落
### 注意事项
- 这是一个简单的俄罗斯方块实现，适合初学者学习和扩展。
- 你可以根据需要添加更多功能，比如计分、关卡加速等。
