python代码实现一个斗兽棋

好的，以下是一个简单的 Python 斗兽棋游戏的实现。

# coding: utf-8

class Animal:
    def __init__(self, name, rank, is_red):
        self.name = name
        self.rank = rank
        self.is_red = is_red
        self.is_alive = True

    def __str__(self):
        return self.name

    def __repr__(self):
        return self.name

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

这是一个简单的斗兽棋游戏，实现了基本的移动和胜利判断。但是由于没有 AI，所以需要两个人手动控制棋子，进行游戏。
