型宣言の標準的なPythonの構文はこれだけです。

内部の型を持つモデルの属性にも同じ標準の構文を使用してください。

そのため、以下の例では`tags`を具体的な「文字列のリスト」にすることができます:

{* ../../docs_src/body_nested_models/tutorial002.py hl[14] *}

## セット型

しかし、よく考えてみると、タグは繰り返すべきではなく、おそらくユニークな文字列になるのではないかと気付いたとします。

そして、Pythonにはユニークな項目のセットのための特別なデータ型`set`があります。

そのため、以下のように、`Set`をインポートして`str`の`set`として`tags`を宣言することができます:

You would have **one single `engine` object** for all your code to connect to the same database.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

Using `check_same_thread=False` allows FastAPI to use the same SQLite database in different threads. This is necessary as **one single request** could use **more than one thread** (for example in dependencies).

Sie können einen `title` hinzufügen:

{* ../../docs_src/query_params_str_validations/tutorial007_an_py310.py hl[10] *}

Und eine `description`:

{* ../../docs_src/query_params_str_validations/tutorial008_an_py310.py hl[14] *}

## Alias-Parameter { #alias-parameters }

Stellen Sie sich vor, Sie möchten, dass der Parameter `item-query` ist.

Wie in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Sie hätten **ein einziges `engine`-Objekt** für Ihren gesamten Code, um sich mit derselben Datenbank zu verbinden.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

Você pode adicionar um `title`:

{* ../../docs_src/query_params_str_validations/tutorial007_an_py310.py hl[10] *}

E uma `description`:

{* ../../docs_src/query_params_str_validations/tutorial008_an_py310.py hl[14] *}

## Parâmetros com alias { #alias-parameters }

Imagine que você queira que o parâmetro seja `item-query`.

Assim:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

    assertThat(iia3.subArray(1, 3).asList()).containsExactly(25L, 125L).inOrder();

    assertThrows(IndexOutOfBoundsException.class, () -> iia3.subArray(-1, 1));
    assertThrows(IndexOutOfBoundsException.class, () -> iia3.subArray(1, 4));
  }

  /*
   * Whenever an implementation uses `instanceof` on a parameter instance, the test has to know that
   * (so much for "black box") and try instances that both do and don't pass the check. The "don't"

У вас должен быть **один объект `engine`** для всей кодовой базы, чтобы подключаться к одной и той же базе данных.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

   * interpreted as outside of the character set of the standard code table until a Shift In
   * character is reached.
   *
   * @since 8.0
   */
  public static final byte SO = 14;

  /**
   * Shift In: A control character indicating that the code combinations which follow shall be

   *
   * @since 8.0
   */

				return

	}
	o = bts

// Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (z BatchJobKV) Msgsize() (s int) {
	s = 1 + 4 + msgp.StringPrefixSize + len(z.Key) + 6 + msgp.StringPrefixSize + len(z.Value)
