having a problem of adding points in Python

I've a little problem, I'm a python beginner and I don't understand one thing. I would like that when the player enters a result other than a number, a loop reminds him that he must enter a number and that if the result of a point voucher is added. My problem is that everything is good except the addition of points, in fact when I enter my 2 good results I stay at 0, I think it's because my points vary between 0 and 1 but I don't know how to solve the problem. If someone could help me ^^

def calcul(x, n):
    global points
    resultats = 0
    while results == 0:
        try:
            resultats = int(input(f"[!] {x} + {n} = "))
            return
        except:
            print("\n Oops ! Le nombre n'est pas valide. Ressaies... \n")
        if resultats == x + n:
            points += 1

calcul(5, 5)
calcul(5, 3)

print(f"\n {points}")
