Il est conçu pour avoir des fonctions qui reçoivent deux paramètres, une "requête" et une "réponse". Ensuite, vous
"lisez" des parties de la requête et "écrivez" des parties dans la réponse. En raison de cette conception, il n'est
pas possible de déclarer des paramètres de requête et des corps avec des indications de type Python standard comme paramètres de fonction.

## Prérequis

FastAPI repose sur les épaules de géants :

* <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a> pour les parties web.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> pour les parties données.

## Installation

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

   * checked exceptions.

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

## Détails techniques

Les versions modernes de Python supportent le **code asynchrone** grâce aux **"coroutines"** avec les syntaxes **`async` et `await`**.

Analysons les différentes parties de cette phrase dans les sections suivantes :

* **Code asynchrone**
* **`async` et `await`**
* **Coroutines**
