how do I make a number only print once but the number keeps on decreasing?

[Killertjuh]

import time
import winsound
 
# User Input
def choose():                            # With a function you have to return your multi var
    user = 'yes'
    plan = input("What Your Plan For Today? : ").lower()
    times = int(input("What Number? : "))
    while True:                   
        choose1 = input("Minute?Second?Hour? : ").lower()
        if 'hour' in choose1:
            multi = times * 3600
            break                 # You dont have to break just use return because you work with function
        elif 'minute' in choose1:
            multi = times * 60
            break                 # You dont have to break just use return because you work with function
        elif 'second' in choose1:
            multi = times
            break                 # You dont have to break just use return because you work with function
        else:
            print("Sorry Sir, There Is No Such Option")
 
# Looping     
while multi > 0 or user == 'yes':         # multi is not defined at this point so this will fail.
    print(multi)                          # you can put this line to linenumber #34
    time.sleep(1)
    multi -= 1                            # multi is not defined so this will fail.
    if multi == 0:
        print("Sir Its Time For You To Do Your Work And Have Nice Day! :)")        
        winsound.PlaySound('C:\\Users\\user\\Documents\\All About Python3 Or Programming\\All 
        Project With Python 3\\background.wav', winsound.SND_FILENAME)
        user = input("Do You Want To Make More Plans? : ").lower() 
        if user == 'yes':
            choose()
        else:
            user = 'no'

I hope this quick change works for you. I`ll didnt test this one.

        if 'hour' in choose1:
            return times * 3600
        elif 'minute' in choose1:
            return times * 60
        elif 'second' in choose1:
            return times

            print(multi)
        else:
            user = 'no'
            # exit()
    else:
        if isinstance(multi, int):
            multi -= 1
