* It contains an `app/main.py` file. As it is inside a Python package (a directory with a file `__init__.py`), it is a "module" of that package: `app.main`.

The same would happen if you had something like a <abbr title='A union between multiple types means "any of these types".'>union</abbr> between different types where one or more of them are not valid Pydantic types, for example this would fail 💥:

//// tab | Python 3.10+

```Python hl_lines="8"

	if w == nil || w.closer == nil {
		return nil
	}
	w.streamWg.Wait()
	err := w.closer()
	w.closer = nil
	return err
}

// Reset and start writing to new writer.
// Close must have been called before this.
func (w *metacacheWriter) Reset(out io.Writer) {
	w.streamErr = nil
	w.creator = func() error {
		s2w := s2.NewWriter(out, s2.WriterBlockSize(w.blockSize), s2.WriterConcurrency(2))

The main feature I wanted from Django REST Framework was the automatic API documentation.

Then I found that there was a standard to document APIs, using JSON (or YAML, an extension of JSON) called Swagger.

And there was a web user interface for Swagger APIs already created. So, being able to generate Swagger documentation for an API would allow using this web user interface automatically.

Auf die gleiche Weise könnten Sie im Exit-Code nach dem `yield` eine `HTTPException` oder ähnliches auslösen.

/// tip | "Tipp"

Dies ist eine etwas fortgeschrittene Technik, die Sie in den meisten Fällen nicht wirklich benötigen, da Sie Exceptions (einschließlich `HTTPException`) innerhalb des restlichen Anwendungscodes auslösen können, beispielsweise in der *Pfadoperation-Funktion*.

Aber es ist für Sie da, wenn Sie es brauchen. 🤓
