Si vous installez Typer CLI, vous pouvez installer la complétion avec :

<div class="termy">

```console
$ typer --install-completion

zsh completion installed in /home/user/.bashrc.
Completion will take effect once you restart the terminal.
```

</div>

### Apps et documentation en même temps

Si vous exécutez les exemples avec, par exemple :

<div class="termy">

```console

///

```Python hl_lines="31"
{!> ../../docs_src/security/tutorial002.py!}
```

////

Notice that we declare the type of `current_user` as the Pydantic model `User`.

This will help us inside of the function with all the completion and type checks.

/// tip

You might remember that request bodies are also declared with Pydantic models.

### Faite en python moderne

Tout est basé sur la déclaration de type standard de **Python 3.8** (grâce à Pydantic). Pas de nouvelles syntaxes à apprendre. Juste du Python standard et moderne.

  // validations is "spec.validations[0].expression"
  optional string fieldRef = 2;

  // The content of type checking information in a human-readable form.
  // Each line of the warning contains the type that the expression is checked
  // against, followed by the type check error from the compiler.
  optional string warning = 3;
}

message MatchCondition {

//     and the version of the actual struct is irrelevant.
//  5. We cannot easily change it.  Because this type is embedded in many locations, updates to this type
//     will affect numerous schemas.  Don't make new APIs embed an underspecified API type they do not control.
//
// Instead of using this type, create a locally provided and used type that is well-focused on your reference.

## Duplicate headers

It is possible to receive duplicate headers. That means, the same header with multiple values.

You can define those cases using a list in the type declaration.

You will receive all the values from the duplicate header as a Python `list`.

For example, to declare a header of `X-Token` that can appear more than once, you can write:

//// tab | Python 3.10+

// FlowDistinguisherMethod specifies the method of a flow distinguisher.
message FlowDistinguisherMethod {
  // `type` is the type of flow distinguisher method
  // The supported types are "ByUser" and "ByNamespace".
  // Required.
  optional string type = 1;
}

// FlowSchema defines the schema of a group of flows. Note that a flow is made up of a set of inbound API requests with
