## List alanları { #list-fields }

Bir attribute’u bir alt tipe sahip olacak şekilde tanımlayabilirsiniz. Örneğin, bir Python `list`:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Bu, `tags`’in bir list olmasını sağlar; ancak list’in elemanlarının tipini belirtmez.

## Tip parametresi olan list alanları { #list-fields-with-type-parameter }

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/cookie_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra cookies**, they will receive an **error** response.
