为什么我在井字游戏中检查获胜者的方法不起作用？

Question

我看到一个人正在玩他的游戏的视频，它很有效。我正在以完全相同的方式检查获胜者，但没有发生任何事情。我使用的是图像而不是字母，但这真的会有所作为。有什么建议？

from tkinter import*

看起来你的问题是当你设置时

buttonList[c]["image"] = picX

buttonList[c]["image"] 的真正值是字符串 "pyimage1"，而 picX 是 tkinter.PhotoImage 类型。鉴于此，如果不是比较诸如

之类的东西，它应该可以解决您的问题

button1["image"] == picX

你应该做类似的事情

 buttonN["image"] == str(picX)

对 picO 做同样的事情。
