If that were Haskell instead of python, it would still work, because tmp is never mutated. So it's not really state in that sense, it's just a binding.

    x input = show tmp
      where tmp = input * 5

It would be a different story if you had something like

    class IntState:
      def __init__(self, val):
        self.val = val
      
      def x(input):
        self.val += input
        return str(val)
