Beachten Sie auch, dass **FastAPI** intelligent genug ist, um zu erkennen, dass `item_id` ein Pfad-Parameter ist und `q` keiner, daher muss letzteres ein Query-Parameter sein.

///

## Query-Parameter Typkonvertierung { #query-parameter-type-conversion }

Sie können auch `bool`-Typen deklarieren, und sie werden konvertiert:

{* ../../docs_src/query_params/tutorial003_py310.py hl[7] *}

Wenn Sie nun zu:

### Sadece modern Python

Tamamiyle standartlar **Python 3.8**'nın type hintlerine dayanıyor (Pydantic'in sayesinde). Yeni bir syntax öğrenmene gerek yok. Sadece modern Python.

var _ ftp.Driver = &ftpDriver{}

// ftpDriver implements ftpDriver to store files in minio
type ftpDriver struct {
	endpoint string
}

// NewFTPDriver implements ftp.Driver interface
func NewFTPDriver() ftp.Driver {
	return &ftpDriver{endpoint: fmt.Sprintf("127.0.0.1:%s", globalMinioPort)}
}

# Modelo de Response - Tipo de Retorno { #response-model-return-type }

Puedes declarar el tipo utilizado para el response anotando el **tipo de retorno** de la *path operation function*.

Puedes utilizar **anotaciones de tipos** de la misma manera que lo harías para datos de entrada en **parámetros** de función, puedes utilizar modelos de Pydantic, list, diccionarios, valores escalares como enteros, booleanos, etc.

	// Claim key-prefix for LDAP attributes
	ldapAttribPrefix = "ldapAttrib_"

	// Role Claim key
	roleArnClaim = "roleArn"

	// STS revoke type claim key
	tokenRevokeTypeClaim = "tokenRevokeType"

	// maximum supported STS session policy size
	maxSTSSessionPolicySize = 2048
)

type stsClaims map[string]any

func (c stsClaims) populateSessionPolicy(form url.Values) error {
	if len(form) == 0 {
		return nil

# WebSockets

When defining WebSockets, you normally declare a parameter of type `WebSocket` and with it you can read data from the client and send data to it.

It is provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi import WebSocket
```
