以下代码在运行时不显示任何错误但不播放警报。 警报文件的扩展名为 .mp3，与项目位于同一文件夹中。 我可能认为时间模块代码有问题 或“设置警报”按钮未接受任何输入。列和行的位置不准确

如 cmets 中所述，您已将其设置为仅当用户在设置闹钟时单击按钮时才播放闹钟。相反，您应该每秒检查一次时间，并在给定时间播放警报：

def alarm_time():
    hrs = int(hrs_opt_ctrl.get())
    min = int(min_opt_ctrl.get())
    tme = tme_ctrl.get()
    if hrs == int(time.strftime('%I')) and min == int(time.strftime('%M')) and tme == time.strftime('%p'):
        # Time is up. Play the sound
        alarm_ringtone = pygame.mixer.music.load('alarm_noise.mp3')
        pygame.mixer.music.play()
        # Don't call after again
    else:
        # Not time, sleep for 1 second
        window.after(1000, alarm_time)

注意，我将所有内容都转换为 int，因为 time.strftime('%I') 和 time.strftime('%M') 返回 0-pre-padded 字符串，而您的选项框没有 0-pre-padded 值，所以 "1" != "01" 等。

更新了多个警报和贪睡的答案。我只是把它放在一起，所以还有很大的改进空间：
