So, we get a Pydantic model from the data in another Pydantic model.

#### Unpacking a `dict` and extra keywords { #unpacking-a-dict-and-extra-keywords }

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.model_dump(), hashed_password=hashed_password)
```

...ends up being like:

		statusCode: 400,
		cause:      err,
	}
}

func errParseExpectedKeyword(err error) *s3Error {
	return &s3Error{
		code:       "ParseExpectedKeyword",
		message:    "Did not find the expected keyword in the SQL expression.",
		statusCode: 400,
		cause:      err,
	}
}

func errParseExpectedTokenType(err error) *s3Error {
	return &s3Error{
		code:       "ParseExpectedTokenType",

- AWS S3's [reserved keywords](https://docs.aws.amazon.com/AmazonS3/latest/dev/s3-glacier-select-sql-reference-keyword-list.html) list is not yet respected.

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).
* Any sequence of arguments that should be passed to the task function in order (`email`).
* Any keyword arguments that should be passed to the task function (`message="some notification"`).

## Dependency Injection { #dependency-injection }

...Python has a little special syntax for that.

Pass `*`, as the first parameter of the function.

Python won't do anything with that `*`, but it will know that all the following parameters should be called as keyword arguments (key-value pairs), also known as <abbr title="From: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>. Even if they don't have a default value.

	// PAXRecords is a map of PAX extended header records.
	//
	// User-defined records should have keys of the following form:
	//	VENDOR.keyword
	// Where VENDOR is some namespace in all uppercase, and keyword may
	// not contain the '=' character (e.g., "GOLANG.pkg.version").
	// The key and value should be non-empty UTF-8 strings.

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

Before that, it only supported the keyword `example` with a single example. That is still supported by OpenAPI 3.1.0, but is deprecated and is not part of the JSON Schema standard. So you are encouraged to migrate `example` to `examples`. 🤓

   *
   * <p>Note that a method may still be effectively "final", or non-overridable when it has no
   * {@code final} keyword. For example, it could be private, or it could be declared by a final

This is a tip.

...it could be translated as:

```
/// tip

Esto es un consejo.

```

...but needs to keep the exact `tip` keyword. If it was translated to `consejo`, like:

```
/// consejo

Esto es un consejo.

///

```

it would change the style to the default one, it would look like:

/// consejo
