我知道有人问了一个类似的问题，我已经尝试了解决问题的所有建议，但我无法解决这个问题。我正在制作一个文档，当按下单选按钮时，会出现第二个单选按钮，其选项将根据对第一个单选按钮的响应而有所不同。问题是选择第一个单选按钮后没有任何反应，变量没有设置为等于值，如果我理解正确，它应该。我什至摆脱了创建按钮并在命令行中添加辅助函数的循环，以设置变量但没有运气......我开始认为这不能使用单选按钮来完成......有谁知道我是否缺少不允许设置变量的内容？

从我在您的代码中看到和测试的内容来看，在我看来，elifs 封装在单击单选按钮时调用的函数中。
为了验证这个理论，我在showchoice函数中放了一个print(var1.get(((，每次点击它都会打印出新的索引。 因此，为了更进一步，我将 label4 创建行也移动到该函数中，并正确更新表单。
所以对我来说，看起来 elifs 块需要封装到一个函数中，每次单击单选按钮时都会调用(并因此更新(。
我希望这有所帮助，或者至少让你走上正确的道路。 我认为没有理由不能或不应该将单选按钮用于您正在做的事情！
