Python 有没有办法使用带有 2 个按钮小部件的 tkinter 在 24 小时和上午下午 12 小时之间切换

我正试图创建一个简单的应用程序，在24小时(军事)和12小时之间切换的上午/下午(标准)时间.我正在使用带有2个按钮小工具的Tkinter，所以如果我按下标准时间按钮，应用程序将切换到标准时间按钮，禁用标准时间按钮，启用军事时间按钮，如果我按下军事时间按钮，应用程序将切换到军事时间，军事按钮将被禁用，并启用标准时间按钮.

我面临的问题是，当我点击应用程序上的按钮小工具切换到军事时间时，它开始失控，我无法切换回标准时间，所以我在这里遇到了障碍.我有两个函数，每个函数用于当一个按钮被按下时，函数被调用，display_standard_time()和display_military_time().我也try 了只使用一个功能来启用和禁用switch ，结果与上面提到的相同.

下面的代码是我目前拥有的代码:

import tkinter as tk
from tkinter import ttk, Label #used to create buttons and widgets
from time import strftime


def display_military_time():
 current_time = strftime('%H: '+'%M: '+'%S '+'%p') + \
                '\n'+ strftime('%b '+  '%d')+ ','  + strftime('%Y')
 display_clock.configure(text=current_time)
 military_time_button["state"] = "disabled"#disable military_button
 standard_time_button["state"] = "normal"#enable standard_button
 display_clock.after(80, display_military_time) #this statement allows to execute display_military_time() after 100ms


def display_standard_time():

 current_time = strftime('%I: ' + '%M: ' + '%S ' + '%p') + \
                '\n'+ strftime('%b '+  '%d')+ ','  + strftime('%Y')
 display_clock.configure(text=current_time)
 standard_time_button["state"] = "disabled"#disable standard_button
 military_time_button["state"] = "normal"#enable military_button
 display_clock.after(80, display_standard_time) 

if __name__ == '__main__':

 main_window = tk.Tk()#Create an instance of tk.Tk class and create an application window

#Place label on window and write text in the window
 main_window.title('Digital Clock') #Name of the window
 main_window.geometry('800x600') #method to change the size and location of the window. , widthxheight±x±y

 display_clock.place(x=50, y=200)
 clock_label = Label(clock_tab,fg='black',font=("arial", 60, 'bold'), text = 'Current Time')
 clock_label.place(x=150, y=100)
 military_time_button = tk.Button(clock_tab,text="MILITARY TIME",bd=10,bg="grey", fg="blue",command=display_military_time,activeforeground="Orange",
