python写个俄罗斯方块游戏

好的，下面是一个简单的俄罗斯方块游戏的Python实现，使用了Pygame库：

import pygame
import random

# 游戏区域宽度和高度
WIDTH = 300
HEIGHT = 600

# 格子大小和边框宽度
BLOCK_SIZE = 30
BORDER_SIZE = 2

# 游戏区域的行数和列数
ROWS = HEIGHT // BLOCK_SIZE
COLS = WIDTH // BLOCK_SIZE

# 方块的种类和形状
SHAPES = [
    [(0, 0), (1, 0), (0, 1), (1, 1)],  # 正方形
    [(0, 0), (1, 0), (2, 0), (3, 0)],  # 长条形
    [(0, 0), (1, 0), (1, 1), (2, 1)],  # Z形
    [(0, 1), (1, 1), (1, 0), (2, 0)],  # 反Z形
    [(0, 0), (1, 0), (2, 0), (1, 1)],  # T形
    [(0, 0), (1, 0), (2, 0), (2, 1)],  # L形
    [(0, 0), (1, 0), (2, 0), (0, 1)]   # 反L形
]

# 方块的颜色
COLORS = [
    (255, 0, 0),     # 红色
    (0, 255, 0),     # 绿色
    (0, 0, 255),     # 蓝色
    (255, 255, 0),   # 黄色
    (255, 0, 255),   # 紫色
    (0, 255, 255),   # 青色
    (255, 165, 0)    # 橙色
]

该游戏的核心是Block类，它表示一个方块。它有一个位置和一个形状，可以绘制自己。它还可以移动和旋转，并检查是否与其他方块碰撞。当方块落到底部时，它会添加到游戏板上，并检查是否有可以消除的行。如果有，它们将被清除，并更新得分。游戏循环处理事件，更新游戏状态并绘制游戏画面。
