Using `Optional[str]` instead of just `str` will let the editor help you detect errors where you could be assuming that a value is always a `str`, when it could actually be `None` too.

`Optional[Something]` is actually a shortcut for `Union[Something, None]`, they are equivalent.

И мы, как разработчики, продолжаем улучшать код — находим баги и добавляем новые возможности (иногда добавляя новые баги 😅).

### Небольшие ошибки обрабатываются автоматически { #small-errors-automatically-handled }

Создавая веб‑API с FastAPI, если в нашем коде возникает ошибка, FastAPI обычно «локализует» её в пределах одного запроса, который эту ошибку вызвал. 🛡
