Is function inheritance possible like class inheritance in python?

Question

from tkinter import *

def alarm_time():
    hrs = int(hrs_opt_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:

The following code doesnt show any error when run but doesnt play the alarm. The alarm file is in .mp3 extension and in the same folder as the project. i probably think that something's wrong in the time module code or the 'Set Alarm' button is not taking any input.The position of columns and rows are not accurate

As mentioned in the comments, you have it setup to only play the alarm iff the user clicks the button at the time the alarm is set to. Instead, you should check the time every second, and play the alarm at the given time:

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)

Note, I convert everything to int because time.strftime('%I') and time.strftime('%M') return 0-pre-padded strings and your option box does not have 0-pre-padded values, so "1" != "01", etc.

Updated answer with multiple alarms and snooze. I just threw this together so there is plenty of room for improvement:

import time

pygame.mixer.init()

window = Tk()
window.geometry('300x200')
window.title('Alarm')

#logo = PhotoImage(file='alarm.gif')

lab_1 = Label(window, text='Alarm Clock', font=('Times',20,'bold')).grid(column=200, row=0)
#lab_2=Label(window,image=logo).grid(column=300,row=0,columnspan=3)
lab_3 = Label(window, text='Hours', font=('Comic',10,'bold')).grid(column=50,row=10, columnspan=3)
lab_4 = Label(window, text='Minutes', font=('Comic',10,'bold')).grid(column=90,row=10, columnspan=3)
