Question

我是初学者程序员，试图创建一个程序，允许用户使用tkinter播放Rock，Paper，Scissors。我没有在课堂上学过tkinter，但这是我的最后一个项目，所以我试图学习一些令人印象深刻的东西。

我能够弄清楚如何定位所有东西，但我的按钮似乎没有做任何事情。退出按钮可以工作，但不是其他任何工作。没有出现解释器错误。任何帮助将不胜感激。

Answer 1

显示不会更改，因为要更改您需要执行的标签winOrLoss的文字：winOrLoss.configure(text=win_or_loss)，只更改win_or_loss不会更改标签内容。

另一种可能性是使用StringVar：

win_or_loss = StringVar()
winOrLoss = Label(textvariable=win_or_loss)

然后，要更改标签内容，请执行win_or_loss.set("new string")。

tkinter按钮不调用函数
