如何在Python中根据RadioButton的点击创建循环

Question

我编写了下面的代码，根据用户的点击来显示某些select选项。因此，如果用户单击第一个单选按钮（值1），只有一个选项将出现，如果他们单击第二个单选按钮（值2），将出现两个等。。。这将一直持续到值10（他们将有10个选项）。你知道吗

如您所见，我为此编写了一个if语句（带有9个elif语句-在上面的代码中，我只发布了第四个值，但它会重复到10）。我意识到我可以通过编写for循环来缩短代码。然而，我被困在如何写这个循环。你知道吗

如果有人能给我指点，那就太棒了！短暂性脑缺血发作

下面是一个在timings函数中可能执行的操作的小示例：

timeHourTwo = StringVar()
timeHourTwo.set(timelistHour[0])
timeMinTwo = StringVar()
timeMinTwo.set(timelistMinute[0])
def recursion(n):
    Label(self.fr, text = "Hour :").grid(row = (5+n), column = 0, sticky = 'e')
    OptionMenu(self.fr, timeHourTwo, *timelistHour).grid(row = (5+n), column = 1, sticky = 'w')
    Label(self.fr, text = "Minute :").grid(row = (5+n), column = 1, sticky = 'e')
    OptionMenu(self.fr, timeMinTwo, *timelistMinute).grid(row = (5+n), column = 2, sticky = 'w') 
    if n > 1:
        recursion(n-1)

它并不完美，因为我无法测试它，而且标签也不会按你的分类（从大到小），但也许它能激励你。希望有帮助！你知道吗

基于此：

def recursion(n):
    print(5+n)
    if n > 1:
        recursion(n-1)

recursion(4)  #Output : 9 8 7 6
