Python3 delay without interruption

Python

Hello.I have the following function:

from threading import Timer
a = 0
def TaskManager():
    global a
    t = Timer( 1, TaskManager )
    t.start()
    if(a == 5):
        t.cancel()
        return
    print("hello")
    a += 1
    

TaskManager()

I don't want to use time.sleep.
So, I want to pass a parameter in TaskManager function ,fox example I want to pass number 5, in order to wait for 5 seconds.
I tried to do this one:

What I have tried:

from threading import Timer
def TaskManager(delay_time):
    
    t = Timer( 1 , TaskManager [delay_time])
    t.start()
    if(delay_time == 0):
        t.cancel()
        return
    print("hello")
    delay_time -= 1
    

TaskManager(5)

in order to delay for 5 sec. but I do not want interruption (like time.sleep() ).
I understand why the code is not working(because recursion never finishes)

I want something like millis() function from arduino( if you know).
How can I do this?
Thanks
