如题怎么将“玩家手持物品未被附魔”设置为条件
如下
player is holding a 4478
我想要玩家手持的4478这个物品是未被附魔的，该怎么写

捕捉一只大冷冷

                if player is holding 4478:
                        player's tool is not enchanted
                        message "手持物4478未附魔"
                if player's tool is a 4478 of sharpness:
                        message "4478附魔了锋利"
                if tool of the player is enchanted with efficiency 2:
                        message "玩家手持的物品附魔了效率2"
                        disenchant the player's tool
                        message "取消其附魔"
                        enchant the player's tool with sharpness 5
                        message "附魔锋利5"
