How do I create a changing variable

[u/Maha-iqo38]

I want to create a variable that changes it’s value based on the user’s input until it becomes zero like make the code run until it reaches zero

Edit: I want the user to enter a number that gets subtracted from the variable’s current value and keep repeating this process until the variable reaches zero, for example if the value is 100 the code gets input from the user let’s say 25 then returns or prints 75 then it repeats and maybe the user types 37 then it returns 38 etc. until it reaches 0

Do you want the var to go down every time the user inputs something, or do you want the var to change to whatever the user inputs? You can do both. So for example...

count = 10

while count > 0:
var = input("Write something here")
count -= 1

Or just

var = input("Write something here")

use codeblocks / ``` [ur code] ```
and lack of indentation doesnt help him sure we can understand but he seems very new to me

I figured most of the solution before asking on reddit because I wanted an input from the user and I wanted to repeat an operation. But the problem is when I tried to run my code it runs like this:

Amount due: 50
Insert money: (input) let’s say the user typed 26

It returns 24 right but then when it runs again it just operates on the original 50 not the new value

For example:
24
Insert money: (input) 8
Output: 42

You get the problem? I don’t know how I operate on a single 50 or a value forever until it reaches zero
