Armour is not working?

Sound like protection value was higher then damage. You simple have to make sure damage is less or greater than zero. Depends how you apply damage to health.

hit = protection - damage
if hit < 0:
    health += hit

else

hit = damage - protection
if hit > 0:
    health -= hit

        self.max_value = value

    def damage(self, value):
        if value > 0:
            self.value -= value

    def fill(self):
        self.value = self.max_value

    def heal(self, value):
        self.value += value
        if self.value > self.max_value:
            self.value = self.max_value
