**FastAPI** целиком основан на Pydantic.

Вы увидите намного больше всего этого на практике в [Руководстве пользователя](tutorial/index.md){.internal-link target=_blank}.

## Аннотации типов в **FastAPI**

## Conclusion

Hiermee heb je basiskennis van wat **omgevingsvariabelen** zijn en hoe je ze in Python kunt gebruiken.

Je kunt er ook meer over lezen op de <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia over omgevingsvariabelen</a>.

## Conclusion

With this you should have a basic understanding of what **environment variables** are and how to use them in Python.

You can also read more about them in the <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia for Environment Variable</a>.

Sie können das jedoch in Ihrem Code dokumentieren, indem Sie Folgendes verwenden: [Zusätzliche Responses](additional-responses.md){.internal-link target=_blank}....

Mas você pode documentar isso no seu código, utilizando: [Retornos Adicionais](additional-responses.md){.internal-link target=_blank}....

If you want to secure your API, there are several better things you can do, for example:

* Make sure you have well defined Pydantic models for your request bodies and responses.

 * limitations under the License.
