用python写一个麻将游戏

好的，这里是一个简单的麻将游戏的代码实现，你可以根据自己的需求进行修改和优化：

import random

class MahjongGame:
    def __init__(self):
        self.tiles = []  # 所有牌
        self.players = []  # 玩家列表

            '1p', '2p', '3p', '4p', '5p', '6p', '7p', '8p', '9p',  # 数牌
            '1m', '2m', '3m', '4m', '5m', '6m', '7m', '8m', '9m',  # 数牌
            '1z', '2z', '3z', '4z', '5z', 6z', '7z',  # 字牌

这个代码中并没有实现完整的麻将规则，只是提供了一个简单的框架，你可以根据需要自行添加和修改。
