* Les **certificats HTTPS** « certifient » un **certain domaine**, mais le protocole et le cryptage se font au niveau TCP, **avant de savoir** quel domaine est traité.

### Comprendre le fonctionnement de l'import { #how-the-importing-works }

La section :

```Python
from .routers import items, users
```

signifie :

* En partant du même package dans lequel vit ce module (le fichier `app/main.py`) (le répertoire `app/`)...
* chercher le sous-package `routers` (le répertoire `app/routers/`)...

Prenons cette application comme exemple :

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

Le paramètre de requête `q` est de type `str | None`, cela signifie qu’il est de type `str` mais peut aussi être `None`, et en effet, la valeur par défaut est `None`, donc FastAPI saura qu’il n’est pas requis.

that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

  If such an object file uses only numerical parameters, data

actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install

## Code asynchrone { #asynchronous-code }

Faire du code asynchrone signifie que le langage 💬 est capable de dire à l'ordinateur / au programme 🤖 qu'à un moment du code, il 🤖 devra attendre que *quelque chose d'autre* se termine autre part. Disons que ce *quelque chose d'autre* est appelé « slow-file » 📝.

This setting will be removed in Go 1.27.

Go 1.22 changed how the runtime interacts with transparent huge pages on Linux.
In particular, a common default Linux kernel configuration can result in
significant memory overheads, and Go 1.22 no longer works around this default.
To work around this issue without adjusting kernel settings, transparent huge
pages can be disabled for Go memory with the
