How do I make a program keep repeating until I input a specific data that stops it?

Question

I'm trying to make a program in python so that when I input a number from 1 to 10, a specific set of program goes on and asks for another number from 1 to 10 and runs another program, until I enter 0(zero) and the program stops.

So my guess was using a while loop but it didn't quite work out.

user_input = input()
user_input = int(user_input)
while user_input != 0:
    (program)
else:
    quit()

Do you mean another python file by saying "another program"? Or it can be a function? — GooDeeJAY, Mar 30 '21 at 13:36
Nope. In just one python file. That program I talked about is actually a really simple program that shows a simple multiplication table for the number I input. — Sun, Mar 30 '21 at 13:38

Try this:

 user_input = int(input())
 while user_input != 0:
     (program)
     user_input = int(input())
 quit()

With your current code you only ask for input once so the loop won't end. This way you can input a new number after every iteration.

I'm having a error saying: int_input = int(int_input()) , TypeError: 'str' object is not callable – Sun Mar 30 '21 at 13:45
you are using int_input(), which is not a function. Just use input() – Seppeke Mar 30 '21 at 13:46
problem solved! Thanks a lot! :) Have a wonderful day, Seppeke <3 – Sun Mar 30 '21 at 13:47
No problem. Just a heads up, it's possible to use something like `input("Enter a number here:)` to automatically print a message when asking for input. – Seppeke Mar 30 '21 at 13:50
I'll try that too :D . Thanks, mate! – Sun Mar 30 '21 at 13:56

Your current program only asks once and then the loop keeps repeating. You need to keep asking for input inside the loop.

def program():
  print("Executing Task....")

user_input = int(input())

while user_input != 0:
    program()
    user_input = int(input())

printf("Program Terminated")

Here it is:

def program():
    pass


user_input = int(input())

while user_input:
    program()
    user_input = int(input())

quit(0)

A different way using iter with a sentinel:

def program(number):
    if number < 0 or number > 10:
        print('Invalid number:', number)
    else:
        print('Valid number:', number)

def quit():
    print('quitting')

def get_number():
    return int(input('Enter a number from 1 to 10: '))

for number in iter(get_number, 0):
    program(number)
else:
    quit()

not_zero = True

while not_zero:
    num = int(input("Enter a number: "))
    if num == 0:
        not_zero = False

you can stop your loop using a boolean value.
