Поскольку доступные значения *параметра пути* определены заранее, интерактивная документация может наглядно их отображать:

### Работа с *перечислениями* в Python { #working-with-python-enumerations }

Значение *параметра пути* будет *элементом перечисления*.

#### Сравнение *элементов перечисления* { #compare-enumeration-members }

And you get editor support everywhere.

Even for items inside of lists:

You couldn't get this kind of editor support if you were working directly with `dict` instead of Pydantic models.

But you don't have to worry about them either, incoming dicts are converted automatically and your output is converted automatically to JSON too.

  private static final int DATASET_SIZE = 1000;
  private static final double ALLOWED_ERROR = 1.0e-10;
  private static final QuantilesAlgorithm REFERENCE_ALGORITHM = QuantilesAlgorithm.SORTING;
  private static final ImmutableSet<QuantilesAlgorithm> NON_REFERENCE_ALGORITHMS =
      Sets.difference(
              ImmutableSet.copyOf(QuantilesAlgorithm.values()),
              ImmutableSet.of(REFERENCE_ALGORITHM))

	if !errors.Is(err, gorm.ErrDuplicatedKey) {
		t.Fatalf("expected err: %v got err: %v", gorm.ErrDuplicatedKey, err)
	}
}

func TestSupportedDialectorWithErrForeignKeyViolated(t *testing.T) {
	tidbSkip(t, "not support the foreign key feature")

	type City struct {
		gorm.Model
		Name string `gorm:"unique"`
	}

	type Museum struct {
		gorm.Model
		Name   string `gorm:"unique"`
		CityID uint

Instead of that, by being an "asynchronous" system, once finished, the task can wait in line a little bit (some microseconds) for the computer / program to finish whatever it went to do, and then come back to take the results and continue working with them.
