Resume and pause button in a countdown timer

Question

## Importing tkinter for the stopwatch.
import tkinter as tk 
## Generate an element from reverse of a given list.

def generator(x):
    for each_element in reversed(x):
        yield each_element
pressed = True

## Take the input of seconds only or minutes and seconds together.

minutes_seconds = input('Enter time in form (minutes seconds). ')

## A function for the working of the timer.

def krejia():
    now1 = next(generator1)

    now_minutes, now_seconds = now1 // 60, now1 % 60
    now_minutes_str, now_seconds_str = str(now1 // 60), str(now1 % 60)

    if now_seconds//10 >= 1:
        label.configure(text = 'Time left: ' + now_minutes_str + ' : ' + now_seconds_str, font = 25)
    else:
        label.configure(text = 'Time left: ' + now_minutes_str + ' : ' + '0' + now_seconds_str, font = 25)
    if pressed:
        if now1 != 0 :
            root.after(1000, krejia)

## For resume and pause button.(a try!)
h = []
for n in range(100):
    h.append(n)
def resume_and_pause_button():
    for each_element in h:
        if int(each_element)%2 == 0:
            pressed = True
        else:
            pressed = False

## if the user gives input in minutes and seconds both, do this.

if ' ' in minutes_seconds: 
    minutes, seconds = minutes_seconds.split(' ')
    real_minutes, real_seconds = int(minutes), int(seconds)

    if real_minutes >= 0 and real_seconds >= 0:
        all_seconds = real_minutes*60 + real_seconds
        time_values = [x for x in range(all_seconds+1)]
        generator1 = generator(time_values)
        root = tk.Tk()

        label = tk.Label(root)
        label.pack()
        krejia()
        tk.Button(root, text = 'resume and pause button', command = resume_and_pause_button).pack()
        root.mainloop()

I'm struggling since a long time with this code and I want to add a resume and pause button to my countdown timer. I know that the resume_and_pause_button() function doesn't really do anything in the code, but yet, every try to do so failed.

Any kind of help will be thankfully accepted.

Everything other than the button perfectly works without any issue, but I have no idea how to drop a resume and pause button in this sort of timer. Any hint/solutions? Thanks! — Book Of Flames, Jun 04 '20 at 13:43
Why do you use a generator? Look at the modul time https://stackoverflow.com/questions/2400262/how-to-create-a-timer-using-tkinter — Thingamabobs, Jun 04 '20 at 15:53
I'd to use generator for adding the button, so that the timer can be stopped at the user's wish. — Book Of Flames, Jun 05 '20 at 03:29
The major problem in the code is the `krejia()` function which is looping itself. I wanted to use for loop instead. This loop prevents any kind of simple interruption e.g. - continue and break statements. — Book Of Flames, Jun 05 '20 at 03:37
