!!! note
    Jeśli nie znasz różnicy, sprawdź [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

Ostatnia ankieta <abbr title="coroczna ankieta przeprowadza w środowisku programistów języka Python">Python developer survey</abbr> jasno wskazuje, że <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">najczęściej używaną funkcjonalnością jest autouzupełnianie w edytorze</a>.

It doesn't matter. **FastAPI** will know what to do.

!!! note
    If you don't know, check the [Async: *"In a hurry?"*](../../async.md#in-a-hurry){.internal-link target=_blank} section about `async` and `await` in the docs.

## Integrated with OpenAPI

    If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Step 5: return the content

**Przypis**:

Jeżeli nie znasz, sprawdź sekcję _"In a hurry?"_ o <a href="https://fastapi.tiangolo.com/async/#in-a-hurry" target="_blank">`async` i `await` w dokumentacji</a>.
