请用python写一个消消乐的游戏

好的，以下是一个简单的消消乐游戏的Python代码：

import random

# 定义方块种类和颜色
block_types = ['O', 'I', 'T', 'S', 'Z', 'L', 'J']
block_colors = {'O': 'yellow', 'I': 'cyan', 'T': 'purple', 'S': 'green', 'Z': 'red', 'L': 'orange', 'J': 'blue'}

# 定义方块种类的形状
block_shapes = {
    'O': [[1, 1], [1, 1]],
    'I': [[1, 1, 1, 1]],
    'T': [[0, 1, 0], [1, 1, 1]],
    'S': [[0, 1, 1], [1, 1, 0]],
    'Z': [[1, 1, 0], [0, 1, 1]],
    'L': [[1, 0], [1, 0], [1, 1]],
    'J': [[0, 1], [0, 1], [1, 1]]
}

# 定义游戏区域大小和方块大小
