为什么我的剪刀石头布游戏中有一段时间 True 循环不起作用？
Why does a while True loop not work in my rock paper scissors game?
我正在尝试制作一款石头剪刀布游戏，其中包含 3 个按钮，可通过导入乌龟在屏幕上点击。一切顺利并且有效，按钮有效，单击某个按钮时屏幕上显示正确的文本。 （我还没有添加计算机选择部分，所以我的代码只是用户输入）但是现在我想添加当你第二次点击一个按钮时，最后一个按钮的文本消失。因为如果你一直点击，文本会停留在那里并且会重叠。所以我想添加一个“你想再玩一次吗？”通过将按钮置于 while True 循环中来输入内容，这样每次单击按钮时它都会询问用户是否要再次播放，但这不起作用。我没有收到任何错误，屏幕打开并为我绘制了所有内容，但我无法单击任何按钮，文本没有显示然后崩溃。如果我删除 while 循环和输入问题，它会再次运行。它应该工作吧？或者这是不可能的？我在其他地方用另一个游戏读过它，所以我不知道为什么它不起作用。这是我的 while True 循环代码。 while True 循环结束了，如果我的代码比应该的长，我很抱歉，我还不知道所有的技巧:

turtle.done()
turtle 的“循环”不需要 while 循环 - turtle.done() 不会“结束”turtle 代码 - 它表示你已“完成”设置并 starts the everlasting turtle mainloop.
你的代码长是因为你一遍又一遍地解决同样的问题，而不是把它放到一个方法中去用参数调用。
你画了 2 个大方框和 3 个小方框，小方框里面的文字也居中，大方框上面的文字不同。
在 turtle 中请求文本输入可以通过 turtle.textinput(...) 更优雅地完成，然后跳到控制台上的 input()。
要退出，请在适当的地方使用 turtle.exitonclick() - 或调用 turtle.bye()。
您的代码重复了很多您应该放入函数中的东西：

# and a global for logic - you can refine that if you want, for demo it works
