### Declare a `List` com um parâmetro de tipo

Para declarar tipos que têm parâmetros de tipo(tipos internos), como `list`, `dict`, `tuple`:

* Importe os do modulo `typing`
* Passe o(s) tipo(s) interno(s) como "parâmetros de tipo" usando colchetes: `[` e `]`

```Python
from typing import List

my_list: List[str]
```

 *  New: `mockwebserver3.SocketPolicy` is now a sealed interface. This is one of several
    backwards-incompatible API changes that may impact early adopters of this alpha API.

 *  New: `mockwebserver3.Stream` for duplex streams.

 *  New: `mockwebserver3.MockResponseBody` for streamed response bodies.

 *  New: `mockwebserver3.MockResponse` is now immutable, with a `Builder`.

 *
 * This nesting is typical but not strict. For example, when calls use "Expect: continue" the
 * request body start and end events occur within the response header events. Similarly,
 * [duplex calls][RequestBody.isDuplex] interleave the request and response bodies.
 *
 * Since connections may be reused, the proxy selection, DNS, and connect events may not be present

!!! tip "팁"
    문법 `{"name", "description"}`은 두 값을 갖는 `set`을 만듭니다.

    이는 `set(["name", "description"])`과 동일합니다.

#### `set` 대신 `list` 사용하기

`list` 또는 `tuple` 대신 `set`을 사용하는 법을 잊었더라도, FastAPI는 `set`으로 변환하고 정상적으로 작동합니다:
