用Python写一段俄罗斯方块游戏代码

好的，以下是一个简单的俄罗斯方块游戏的代码示例，使用 Python 语言编写，希望能对你有所帮助：

import pygame
import random

# 游戏区域大小
WINDOW_WIDTH, WINDOW_HEIGHT = 480, 600
# 方块大小
BLOCK_SIZE = 20
# 方块颜色
COLORS = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0), (255, 0, 255), (0, 255, 255), (255, 255, 255)]
# 方块形状
BLOCKS = [
    [[1, 1],
     [1, 1]],
    [[1, 0, 0],
     [1, 1, 1]],
    [[0, 0, 1],
     [1, 1, 1]],
    [[1, 1, 0],
     [0, 1, 1]],
    [[0, 1, 1],
     [1, 1, 0]],
    [[0, 1, 0],
     [1, 1, 1]],
    [[1, 1, 1, 1]]
]

class Block:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.color = random.choice(COLORS)
        self.shape = random.choice(BLOCKS)
        self.rotation = 0

        shape = self.block.get_current_shape()
        for y, row in enumerate(shape):

        return True

                if self.block.y + y < 0:
                    continue
                if shape[y][x] and self.board[self.block.y + y][self.block.x + x]:

if __name__ == '__main__':
    game = Game()
    game.run()

这个代码非常基本，只包含了游戏逻辑的核心部分，如果需要完整的游戏，还需要添加一些额外的功能，例如游戏菜单、音效、排行榜等等。
