И тогда вам не придётся задумываться о названиях вроде `Optional` и `Union`. 😎

#### Generic-типы { #generic-types }

Типы, которые принимают параметры типов в квадратных скобках, называются **Generic-типами** или **Generics**, например:

//// tab | Python 3.10+

Вы можете использовать те же встроенные типы как generics (с квадратными скобками и типами внутри):

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

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

#### Generic types { #generic-types }

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

//// tab | Python 3.10+

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

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

### `///` admonitions

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
2) Many Traditional Chinese docs currently omit titles in `///` blocks; that is OK.
3) If a generic title is present, prefer these canonical titles:

- `/// note | 注意`

Notes:

- `details` blocks exist; keep `/// details` as-is and translate only the title after `|`.
- Example canonical titles used in existing docs:

* **`400 - 499`** are for "Client error" responses. These are the second type you would probably use the most.
    * An example is `404`, for a "Not Found" response.
    * For generic errors from the client, you can just use `400`.

Und dann müssen Sie sich nicht mehr um Namen wie `Optional` und `Union` kümmern. 😎

#### Generische Typen { #generic-types }

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

//// tab | Python 3.10+

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

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

RequestErrorModel: type[BaseModel] = create_model("Request")
WebSocketErrorModel: type[BaseModel] = create_model("WebSocket")

### Tipos genéricos con parámetros de tipo { #generic-types-with-type-parameters }

Hay algunas estructuras de datos que pueden contener otros valores, como `dict`, `list`, `set` y `tuple`. Y los valores internos también pueden tener su propio tipo.

* `int`
* `float`
* `bool`
* `bytes`
