O **FastAPI** é todo baseado nesses type hints, eles oferecem muitas vantagens e benefícios.

Mas mesmo que você nunca use o **FastAPI**, você se beneficiaria de aprender um pouco sobre eles.

/// note | Nota

Se você é um especialista em Python e já sabe tudo sobre type hints, pule para o próximo capítulo.

## Motivação { #motivation }

Vamos começar com um exemplo simples:

* Fazer uma **pergunta** ou perguntar sobre um **problema**.
* Sugerir uma nova **funcionalidade**.

**Nota**: se você fizer isso, então vou pedir que você também ajude outras pessoas. 😉

## Revise Pull Requests { #review-pull-requests }

Você pode me ajudar revisando pull requests de outras pessoas.

	Sign       []byte `msg:"s"`
	OldDataDir string `msg:"od"` // contains '<uuid>', it is designed to be passed as value to Delete(bucket, pathJoin(object, dataDir))
}

const (
	checkPartUnknown int = iota

	// Changing the order can cause a data loss
	// when running two nodes with incompatible versions
	checkPartSuccess
	checkPartDiskNotFound
	checkPartVolumeNotFound
	checkPartFileNotFound

Entonces, declara tus *path operation functions* con `async def` así:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note | Nota

Solo puedes usar `await` dentro de funciones creadas con `async def`.

// ValueSource represents the source of a config parameter value.
type ValueSource uint8

// Constants for ValueSource
const (
	ValueSourceAbsent ValueSource = iota // this is an error case
	ValueSourceDef
	ValueSourceCfg
	ValueSourceEnv
)

// ResolveConfigParam returns the effective value of a configuration parameter,

/// note
Here goes a note
///

To translate it, keep the same line and add the translation after a vertical bar.

For example, if you were translating to Spanish, you would write:

/// note | Nota

Some examples in Spanish:

Source (English):

/// tip

Result (Spanish):

/// tip | Consejo

Source (English):

/// details | Preview

Result (Spanish):

		queries: []string{"analytics", ""},
	},
}

// Set of s3 handler options as bit flags.
type s3HFlag uint8

	// and body are traced.
	traceHdrsS3HFlag

	// when provided, disables throttling via the `maxClients` middleware.
	noThrottleS3HFlag

		return
	}

	for _, exp := range f.ExpFunc {
