Но если вам любопытен именно этот пример и всё ещё интересно, вот немного подробностей.

#### Строка и `value.startswith()` { #string-with-value-startswith }

Заметили? Метод строки `value.startswith()` может принимать кортеж — тогда будет проверено каждое значение из кортежа:

It will perform the validation of the compound data, and will document it like that for the OpenAPI schema and automatic docs.

## Singular values in body { #singular-values-in-body }

The same way there is a `Query` and `Path` to define extra data for query and path parameters, **FastAPI** provides an equivalent `Body`.
