我不知道我做错了什么，（就编码而言，我还是一个初学者），但是del rooms[currm]['Item']行实际上并没有删除项目。我遵循了大部分的指南，但是我使用的指南没有删除项目位。所以任何帮助都将受到欢迎。使用Python 3.

item = None
direction = 'direction'

    # print main menu and the commands

                  Add to Inventory: Get {'Item'}\n\n''')

                print('No item here')
        except:
            pin = f'That {item} is located elsewhere'

最初拾取物品的结果是：

Enter your move:
get armor

Current Position: Guard House
Inventory : ['Armor']
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Armor obtained!

然而，如果我尝试再次拿起该项目，它的行为就像我从来没有拿起它开始，并返回相同的结果。我不是100%，我期望发生的是，但基本上这是我想要的结果。

Enter your move:
get armor

No item here

我试着把它移回与if item == rooms[currm]['Item']:一致，看看这是否是问题所在，但也不起作用。

else:
                    del rooms[currm]['Item']  # deletes item if already obtained
