石头，纸，剪刀-PythonTkinter

如何解决石头，纸，剪刀-PythonTkinter

因此，我有一个石头，纸和剪刀的小项目用于学习（特别是使用Tkinter来创建GUI），并且遇到了麻烦。我已经在Python终端中检查了计数器是否在工作，但是它没有更新Label，所以计数器在界面中停留在0。我尝试了一切，然后搜索了其他程序，例如我的程序，它们做了同样的事情，我只是不知道该怎么办。谁能为我解决这个问题？ （对此，代码有点过于广泛，对此感到抱歉。另外，一些文本是葡萄牙语的，但我认为这并不重要。）

解决方法

您的标签未更新，因为您尚未将其连接到任何文本，这意味着它不知道更改后会显示什么文本。 您可以使用StringVar（）做什么，只要更改文本，它就会自动更新标签。

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
  <button v-on:click="showCheckout">Click Me</button>
  {{showProduct}}
</div>

因此，每当调用counter.set时，标签就会自动使用新的计数器值进行更新。 初始化标签时，您可以提供一个textvariable参数，该参数用于标签更改时显示的文本，Tkinter会自动为我们更新它。

您可以在这里how to change/update Tkinter label

了解更多信息 ,

欢迎堆栈溢出。

标签未更新的原因是在初始化时已为其赋予固定值。要更新标签的值，您可以使用以下两种选择：

1. 如@Mahendra Suthar所述，在标签上附加textvariable并稍后更新标签的值，或在标签上使用.update()方法。
2. 您可以使用.configure或label.configure(text = 'Updated_text')来使用label['text'] = 'Updated_text'方法来设置文本的值。

这是您代码的有效示例（由于无法使用，因此我将图像更改为文本）
