# Guide de l'utilisateur avancé

## Caractéristiques supplémentaires

Le [Tutoriel - Guide de l'utilisateur](../tutorial/index.md){.internal-link target=_blank} devrait suffire à vous faire découvrir toutes les fonctionnalités principales de **FastAPI**.

Dans les sections suivantes, vous verrez des options, configurations et fonctionnalités supplémentaires.

!!! note "Remarque"
    Les sections de ce chapitre ne sont **pas nécessairement "avancées"**.

## Requisiti

Python 3.6+

FastAPI è basata su importanti librerie:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> per le parti web.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> per le parti dei dati.

## Installazione

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

labels.popular_word_word_enabled	=	Réponse de mot populaire
labels.supported_search_web	=	Web
labels.supported_search_none	=	Indisponible
labels.purge_search_log_day	=	Purger le journal de recherche avant
labels.purge_job_log_day	=	Purger le journal des tâches avant
labels.purge_user_info_day	=	Purger le journal utilisateur avant
labels.purge_by_bots	=	Nom des robots pour la purge
labels.log_level	=	Niveau de journalisation

```Python hl_lines="8"
{!../../../docs_src/path_params_numeric_validations/tutorial004.py!}
```

## 数値の検証: より大きいと小なりイコール

以下も同様です:

* `gt`: より大きい（`g`reater `t`han）
* `le`: 小なりイコール（`l`ess than or `e`qual）

```Python hl_lines="9"
{!../../../docs_src/path_params_numeric_validations/tutorial005.py!}
```

## 数値の検証: 浮動小数点、 大なり小なり

数値のバリデーションは`float`の値に対しても有効です。

"histogram_quantile(0.5, sum(rate(pilot_proxy_convergence_time_bucket[1m])) by (le))", "format": "time_series", "intervalFactor": 1, "legendFormat": "p50 ", "refId": "A" }, { "expr": "histogram_quantile(0.9, sum(rate(pilot_proxy_convergence_time_bucket[1m])) by (le))", "format": "time_series", "intervalFactor": 1, "legendFormat": "p90", "refId": "B" }, { "expr": "histogram_quantile(0.99, sum(rate(pilot_proxy_convergence_time_bucket[1m])) by (le))", "format": "time_series", "intervalFactor": 1, "legendFormat":...

Este es solo un **tutorial corto** sobre los Python type hints. Solo cubre lo mínimo necesario para usarlos con **FastAPI**... realmente es muy poco lo que necesitas.

Todo **FastAPI** está basado en estos type hints, lo que le da muchas ventajas y beneficios.

Pero, así nunca uses **FastAPI** te beneficiarás de aprender un poco sobre los type hints.

		"Total number of requests canceled by the client", "name", "type")

	apiRequestsTTFBSecondsDistributionMD = NewCounterMD(apiRequestsTTFBSecondsDistribution,
		"Distribution of time to first byte across API calls", "name", "type", "le")

	apiTrafficSentBytesMD = NewCounterMD(apiTrafficSentBytes,
		"Total number of bytes sent", "type")
	apiTrafficRecvBytesMD = NewCounterMD(apiTrafficRecvBytes,
		"Total number of bytes received", "type")
)

    ```

## Number validations: greater than and less than or equal

The same applies for:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual
