But Python has a specific way to declare lists with internal types, or "type parameters":

### Import typing's `List` { #import-typings-list }

In Python 3.9 and above you can use the standard `list` to declare these type annotations as we'll see below. 💡

But in Python versions before 3.9 (3.6 and above), you first need to import `List` from standard Python's `typing` module:

{* ../../docs_src/body_nested_models/tutorial002.py hl[1] *}

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e instalá-lo, por exemplo:

```console
$ pip install httpx
```

///

Importe `TestClient`.

Crie um `TestClient` passando seu aplicativo **FastAPI** para ele.

Crie funções com um nome que comece com `test_` (essa é a convenção padrão do `pytest`).
