if "-" in use: TypeError: argument of type ‘int’ is not iterable

this is my code

n1 = 800
use = []
use2 = []

while use != n1:
  use = int(input("Money: "))
  use2.append(use)
  print("The money that left:",800 - sum(use2))

  if "-" in use:
    print('ok')

>Solution :

n1 = 800
use = []
use2 = []

while use != n1:
  use = input("Money: ")
  use2.append(int(use))
  print("The money that left:",800 - sum(use2))

  if "-" in use:
    print('ok')

Worked for me!
