#### `Hero` - *테이블 모델*

다음으로 실제 *테이블 모델*인 `Hero`를 생성합니다. 이 모델은 다른 모델에는 항상 포함되는 건 아닌 **추가 필드**를 포함합니다:

* `id`
* `secret_name`

`Hero`는 `HeroBase`를 상속하므로 `HeroBase`에 선언된 필드도 포함합니다. 따라서 `Hero`는 다음 **필드들도** 가지게 됩니다:

* `id`
* `name`
* `age`
* `secret_name`

خط زیر را به این صورت تغییر دهید:

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

از:

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

به:

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

                }
            }
            return sb.toString();
        }
        return s;
    }

    /**
     * Returns the simple name of the dictionary file.
     *
     * @return The file name without the path.
     */
    public String getSimpleName() {
        return new File(path).getName();
    }

    /**

  public static <T extends @Nullable Object> T[] newArray(Class<@NonNull T> type, int length) {
    return (T[]) Array.newInstance(type, length);
  }

  /**
   * Returns a new array of the given length with the same type as a reference array.
   *
   * @param reference any array of the desired type
   * @param length the length of the new array
   */
  public static <T extends @Nullable Object> T[] newArray(T[] reference, int length) {

Por exemplo, você poderia ter um arquivo `main.py` com:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```
