有人可以解释为什么没有输出吗？

Question

抱歉，标题含糊。我想知道为什么当我输入“环顾四周”时什么也没发生。该代码将保持运行状态，但不会输出任何应有的内容。

        if PlayerPos==51: # Inside cottage
            choice=input("You stand in the middle of the small, neat home, what do you do?")
            checker=choice.lower().split()
            for word in checker:
                if word in directions:
                    print("You can move no further")
            if choice.lower()=="go outside"or"go out"or"exit":
                PlayerPos=0
            elif choice.lower()=="look around":
                print("You find two bread loafs and a small kitchen knife")
                inventory.append("Bread Loaf")
                inventory.append("Bread Loaf")
                inventory.append("Kitchen Knife")
                print(inventory)
                continue
            else:
                print("I don't understand. Please reword your command")
                continue```
