=== "Python 3.10 і вище"

    ```Python hl_lines="1"

    ```

#### Generic типи

Ці типи, які приймають параметри типу у квадратних дужках, називаються **Generic types** or **Generics**, наприклад:

=== "Python 3.8 і вище"

    * `List`
    * `Tuple`
    * `Set`
    * `Dict`
    * `Union`
    * `Optional`

#### Generic-типы

Эти типы принимают параметры в квадратных скобках:

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...и др.

называются **Generic-типами** или **Generics**.

### Классы как типы

Вы также можете объявить класс как тип переменной.

```

And then you won't have to worry about names like `Optional` and `Union`. 😎

#### Generic types

These types that take type parameters in square brackets are called **Generic types** or **Generics**, for example:

=== "Python 3.10+"

    You can use the same builtin types as generics (with square brackets and types inside):

    * `list`
    * `tuple`
    * `set`
    * `dict`

We will probably still want to keep it for OpenAPI in general, as that will ensure that the operation IDs are **unique**.

But for the generated client we could **modify** the OpenAPI operation IDs right before generating the clients, just to make those method names nicer and **cleaner**.

### Run Automatically on Startup

In general, you will probably want the server program (e.g. Uvicorn) to be started automatically on server startup, and without needing any **human intervention**, to have a process always running with your API (e.g. Uvicorn running your FastAPI app).

```

`Optional[str]`을 `str` 대신 쓰게 되면, 특정 값이 실제로는 `None`이 될 수도 있는데 항상 `str`이라고 가정하는 상황에서 에디터가 에러를 찾게 도와줄 수 있습니다.

#### Generic(제네릭) 타입

이 타입은 대괄호 안에 매개변수를 가지며, 종류는:

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...등등

위와 같은 타입은 **Generic(제네릭) 타입** 혹은 **Generics(제네릭스)**라고 불립니다.

### 타입으로서의 클래스

변수의 타입으로 클래스를 선언할 수도 있습니다.

이름(name)을 가진 `Person` 클래스가 있다고 해봅시다.

    ```Python hl_lines="10"
    {!> ../../../docs_src/query_params_str_validations/tutorial014.py!}
    ```

## Recap

You can declare additional validations and metadata for your parameters.

Generic validations and metadata:

* `alias`
* `title`
* `description`
* `deprecated`

Validations specific for strings:

* `min_length`
* `max_length`
* `pattern`

    Use the chat only for other general conversations.

### Don't use the chat for questions

Keep in mind that as chats allow more "free conversation", it's easy to ask questions that are too general and more difficult to answer, so, you might not receive answers.

#### Generische Typen

Diese Typen, die Typ-Parameter in eckigen Klammern akzeptieren, werden **generische Typen** oder **Generics** genannt.

=== "Python 3.10+"

    Sie können die eingebauten Typen als Generics verwenden (mit eckigen Klammern und Typen darin):

    * `list`
    * `tuple`
    * `set`
    * `dict`

Les types qui peuvent contenir des paramètres de types entre crochets, comme :

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...et d'autres.

sont appelés des **types génériques** ou **Generics**.

### Classes en tant que types

Vous pouvez aussi déclarer une classe comme type d'une variable.

Disons que vous avez une classe `Person`, avec une variable `name` :

```Python hl_lines="1-3"
