As a rule of thumb, if your `Collection` type is a list, you most likely should be using a different type to flatten the list.

Komenda `uvicorn main:app` odnosi się do:

* `main`: plik `main.py` ("moduł" w Pythonie).
* `app`: obiekt stworzony w `main.py` w lini `app = FastAPI()`.
* `--reload`: spraw by serwer resetował się po każdej zmianie w kodzie. Używaj tego tylko w środowisku deweloperskim.
