A forma mais comum de fazer isso é ter um arquivo `requirements.txt` com os nomes dos pacotes e suas versões, um por linha.

Você, naturalmente, usaria as mesmas ideias que você leu em [Sobre versões do FastAPI](versions.md) para definir os intervalos de versões.

Por exemplo, seu `requirements.txt` poderia parecer com:

```
fastapi[standard]>=0.113.0,<0.114.0

```

Os valores dos parâmetros na sua função serão:

* `skip=20`: Por que você definiu isso na URL
* `limit=10`: Por que esse era o valor padrão

## Parâmetros opcionais { #optional-parameters }

Da mesma forma, você pode declarar parâmetros de consulta opcionais, definindo o valor padrão para `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}
