Code in question:def find_slot(self, key, index):        prob_range = self.get_prob_range(index)        for prob_index in prob_range:            if self.arr[prob_index] is None:                return prob_index            if self.arr[prob_index][0] == key:                return prob_index        raise Exception("Hashmap full") ```Maybe this can fix it:def find_slot(self, key, index):        first_slot = None        prob_range = self.get_prob_range(index)        for prob_index in prob_range:            if first_slot == None and self.arr[prob_index] is None:                first_slot = prob_index            if self.arr[prob_index][0] == key:                return prob_index        if first_slot is not None:           return first_slot        raise Exception("Hashmap full")
