```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

O FastAPI é inteligente o suficiente (na verdade, o Pydantic é inteligente o suficiente) para perceber que, embora `description`, `tax` e `tags` tenham os mesmos valores que os padrões, eles foram definidos explicitamente (em vez de retirados dos padrões).

}

// GetTaggingConfig returns configured tagging config
// The returned object may not be modified.
func (sys *BucketMetadataSys) GetTaggingConfig(bucket string) (*tags.Tags, time.Time, error) {
	meta, _, err := sys.GetConfig(GlobalContext, bucket)
	if err != nil {
		if errors.Is(err, errConfigNotFound) {
			return nil, time.Time{}, BucketTaggingNotFound{Bucket: bucket}
		}

```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

dann ist FastAPI klug genug (tatsächlich ist Pydantic klug genug) zu erkennen, dass, obwohl `description`, `tax`, und `tags` die gleichen Werte haben wie ihre Defaultwerte, sie explizit gesetzt wurden (statt dass sie von den Defaultwerten genommen wurden).

Вы можете объявить `examples` для модели Pydantic, которые будут добавлены в сгенерированную JSON Schema.

# Unpack the wheel to get all the file contents. The pure python wheel we built

# renaming the wheels as uploading to PyPI would fail with "File already exists"

    while (StrictMath.pow(2.0, trueLog2) > d) {
      trueLog2 = StrictMath.nextAfter(trueLog2, Double.NEGATIVE_INFINITY);
    }
    if (StrictMath.abs(StrictMath.pow(2.0, trueLog2) - d)
        > StrictMath.abs(StrictMath.pow(2.0, StrictMath.nextUp(trueLog2)) - d)) {
      trueLog2 = StrictMath.nextUp(trueLog2);

    return trueLog2;
  }

We had this type annotation:

//// tab | Python 3.10+

```Python
q: str | None = None
```

////

//// tab | Python 3.9+

```Python
q: Union[str, None] = None
```

////

What we will do is wrap that with `Annotated`, so it becomes:

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

////

//// tab | Python 3.9+

```Python

//// tab | Python 3.9+

```Python hl_lines="1"
async def needy_dependency(fresh_value: Annotated[str, Depends(get_value, use_cache=False)]):
    return {"fresh_value": fresh_value}
```

////

//// tab | Python 3.9+ без Annotated
