我是编码新手，最近开始学习python。我的第一个挑战是制作一个井字游戏。以下是我的游戏代码，除了没有赢家(即游戏平局(外，一切都很好；我想显示no body has won the game.我已经尝试在不同的地方加入else。但是，他们没有帮助。这是我的密码。
# a dictionary to display the grid
grid = {
'1':'1', '2':'2', '3':'3',
'4':'4', '5':'5', '6':'6',
'7':'7', '8':'8', '9':'9'

不是设置result=None，而是设置result='Nobody'。
从你的逻辑来看，你只在有人获胜的情况下设置结果，这将把结果的默认值留给任何人。

对不起，我有点忘乎所以，在证明我的解决方案时，我重写了你的游戏逻辑。要么接受它，要么放弃它，但它现在效果很好，也许你可以把它作为一个例子来修复你自己的问题。
