Essayez de changer la ligne contenant :

```Python
    return {"item_name": item.name, "item_id": item_id}
```

... de :

```Python
        ... "item_name": item.name ...
```

... vers :

```Python
        ... "item_price": item.price ...
```

Solo tocamos los conceptos básicos, pero ya te haces una idea de cómo funciona todo.

Intenta cambiar la línea con:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...desde:

```Python
        ... "item_name": item.name ...
```

...a:

```Python
        ... "item_price": item.price ...
```

- 提供兩種交互式文件介面。

雖然我們只敘述了表面的功能，但其實你已經理解了它是如何執行。

試著修改以下程式碼：

```Python
    return {"item_name": item.name, "item_id": item_id}
```

從：

```Python
        ... "item_name": item.name ...
```

修改為：

```Python
        ... "item_price": item.price ...
```

然後觀察你的編輯器，會自動補全並且還知道他們的型別：

Nós apenas arranhamos a superfície, mas você já tem idéia de como tudo funciona.

Experimente mudar a seguinte linha:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...de:

```Python
        ... "item_name": item.name ...
```

...para:

```Python
        ... "item_price": item.price ...
```
