I have used after in an application to update time, date, weather and other things. But I am running into difficulty when trying to run multiple timers using after. The timer stops, when another timer button is clicked.
import time
import datetime
from tkinter import *
import tkinter as tk
from tkinter import messagebox
import tkinter.font as TkFont
from time import strftime
def stop_drink():
global count_flag_drink
count_flag_drink = False

global count_flag_drink
count_flag_drink = True
start = time.time()
time.process_time()
while True:
if count_flag_drink == False:
break
elapsed = time.time() - start
hours, mins, secs = str(datetime.timedelta(seconds=elapsed)).split(':')
hour_drink.set(hours)
minute_drink.set(mins)
second_drink.set(secs.split('.')[0])
time.sleep(0.1)
root.update()
root.after(1000, count_up_drink)
def count_down_drink():
global count_flag_drink
count_flag_drink = True
try:
temp = int(hour_drink.get()) * 3600 + \
int(minute_drink.get()) * 60 + int(second_drink.get())
except:
print("Please input the right value")
while temp > -1:
if count_flag_drink == False:
break
mins, secs = divmod(temp, 60)
hours = 0
if mins > 60:
hours, mins = divmod(mins, 60)
hour_drink.set(f"{hours:2d}")
minute_drink.set(f"{mins:2d}")
second_drink.set(f"{secs:2d}")
root.update()
time.sleep(1)
if (temp == 0):

UPDATE. I found this solution to be easily extendible for my purposes. [timer using classses][1]
