To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.

#### Newer versions of Python

The syntax using `typing` is **compatible** with all versions, from Python 3.6 to the latest ones, including Python 3.9, Python 3.10, etc.

A round of applause to them. 👏 🙇

  Alice did not much like keeping so close to her:  first,
because the Duchess was VERY ugly; and secondly, because she was
exactly the right height to rest her chin upon Alice's shoulder,
and it was an uncomfortably sharp chin.  However, she did not
like to be rude, so she bore it as well as she could.

  `The game's going on rather better now,' she said, by way of
keeping up the conversation a little.

### Импортируйте `List` из модуля typing

В Python 3.9 и выше вы можете использовать стандартный тип `list` для объявления аннотаций типов, как мы увидим ниже. 💡

Но в версиях Python до 3.9 (начиная с 3.6) сначала вам необходимо импортировать `List` из стандартного модуля `typing` в Python:

```Python hl_lines="1"
{!> ../../../docs_src/body_nested_models/tutorial002.py!}
```

 * at one time; if a value is not available to be edited then [edit] will return null.
 *
 *  * When an entry is being **created** it is necessary to supply a full set of values; the empty
 *    value should be used as a placeholder if necessary.
 *
 *  * When an entry is being **edited**, it is not necessary to supply data for every value; values
 *    default to their previous value.
 *

   * request bodies.
