#### `HeroBase` – die Basisklasse { #herobase-the-base-class }

Fangen wir mit einem `HeroBase`-Modell an, das alle **Felder hat, die von allen Modellen geteilt werden**:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### `Hero` – das *Tabellenmodell* { #hero-the-table-model }

#### `HeroBase` - la classe de base { #herobase-the-base-class }

Commençons avec un modèle `HeroBase` qui a tous les **champs partagés** par tous les modèles :

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### `Hero` - le *modèle de table* { #hero-the-table-model }

						columnType.Name(), length, 100, columnType)
				}
			case "age":
				if v, ok := columnType.DefaultValue(); !ok || v != "18" {
					t.Fatalf("column age default value should be correct, name: %v, column: %#v", columnType.Name(),
						columnType)
				}
				if v, ok := columnType.Comment(); !ok || v != "my age" {
					t.Fatalf("column age comment should be correct, name: %v, column: %#v", columnType.Name(),
						columnType)

Так как редактор кода знает типы переменных, вы получаете не только автозавершение, но и проверки ошибок:

Теперь вы знаете, что нужно исправить — преобразовать `age` в строку с помощью `str(age)`:

{* ../../docs_src/python_types/tutorial004_py310.py hl[2] *}

## Объявление типов { #declaring-types }

Вы только что увидели основное место, где объявляют подсказки типов — параметры функции.

  @Test
  fun cacheHit() {

          headersOf(
            "ETag",
            "v1",

        .newBuilder()
        .cache(cache)

Jetzt, da Sie wissen, dass Sie das reparieren müssen, konvertieren Sie `age` mittels `str(age)` in einen String:

different.  But if I'm not the same, the next question is, Who in
the world am I?  Ah, THAT'S the great puzzle!'  And she began
thinking over all the children she knew that were of the same age
as herself, to see if she could have been changed for any of
them.

  `I'm sure I'm not Ada,' she said, `for her hair goes in such
long ringlets, and mine doesn't go in ringlets at all; and I'm

Porque el editor conoce los tipos de las variables, no solo obtienes autocompletado, también obtienes chequeo de errores:

Ahora sabes que debes corregirlo, convertir `age` a un string con `str(age)`:

{* ../../docs_src/python_types/tutorial004_py310.py hl[2] *}

Agora você sabe que precisa corrigi-la, convertendo `age` em uma string com `str(age)`:

## Declarando tipos { #declaring-types }

Você acabou de ver o local principal para declarar type hints. Como parâmetros de função.
