如何使用Tkinter在python中的不同时间显示不同组的单选按钮？

根据计数的大小，如何使我的按钮在不同时间显示？我想要的是，当单击第一组按钮时，它会显示一组不同的按钮，然后单击这些按钮后，会弹出第三组按钮。

Python没有单选按钮；你在用图书馆吗？如果有，哪个？Tkinter有单选按钮是的，对不起，我用的是Tkinter。你能说得更具体些吗？您是想让用户选择时间[12:00 am/pm]，还是想让Tkinter在用户选择hr，然后分钟帧打开，然后是am/pm时刷新新帧/画布。你可以使用下拉菜单来处理这个问题。我正在尝试在用户选择小时、分钟和am/pm时刷新CANA。通常每小时有12个按钮（每小时一个），每分钟有60个按钮，然后上午/下午有2个按钮，但在这个例子中我把它缩短了。对不起，你能解释一下为什么selectedHour（）方法需要“count”变量吗？对不起，我对这个很陌生。为什么它不像我那样工作？使用count+=1可根据当前的计数更改显示的按钮，您可以使用count递增1的selectedHour（）函数，但不向其传递count参数。您可以使用count递增1的selectedHour（）函数，但不向其传递count参数。Python逐行运行，因此您以前使用的if语句将只运行一次，返回是不可能的，这就是函数的作用所在，它们有助于您在执行多次操作时不必重复自己的操作。您还可以使用while循环

while（count>=1）

，并将if语句放在该循环中，但您需要一个停止条件，以便while循环停止运行。
