私はLPTHWに追加のクレジットを割り当てようとしていますが、機能の真の目的がわからないものをおそらく試していると思います。特に私のコードでは、ユーザーがアイテムを購入すると、現在のアイテムリストからアイテムがポップオフされ、新しいアイテムに置き換えられます。購入機能をテストしたところ、インデックス エラーが発生しました。これを正しく機能させる方法についてのアイデアはありますか?

あなたのbuy_weapons関数では、あなたのコードをデバッグするためだけに、最初の行を「武器を印刷する」にしてください。. . あなたはおそらくあなたが合格していると思っているものを合格していません

また、Python を学習しているときに、私たちのほとんどが最初に言語を学習するときに行ったのと同じことを行っているときに、いくつかのデータ構造を調べたいと思うかもしれません。まだオブジェクトの準備ができていないと思いますが、ネストされた辞書を使用する価値があるかもしれません。

weapons = {1 : {'sword': {'name':'name here',
                            'price': 123},
                  'blunt': {'name':'name here',
                            'price': 123},
                  'agile': {'name':'name here',
                            'price': 123},
                  },
           2 : {'sword': {'name':'name here',
                            'price': 123},
                  'blunt': {'name':'name here',
                            'price': 123},
                  'agile': {'name':'name here',
                            'price': 123},
                  },
          #add levels as you need
          }

基本的に、名前と価格で、レベル、次に武器の種類を追跡する派手なルックアップ型のものを作成していて、次のようにアクセスできます。

level = 1
type = 'sword'
weaponname = weapons[level][type]['name']
weaponprice = weapons[level][type]['price']
