### Krok 2: utwórz instancję `FastAPI`

{*../../docs_src/first_steps/tutorial001.py hl[3] *}

Zmienna `app` będzie tutaj "instancją" klasy `FastAPI`.

Będzie to główny punkt interakcji przy tworzeniu całego interfejsu API.

Ta zmienna `app` jest tą samą zmienną, do której odnosi się `uvicorn` w poleceniu:

<div class="termy">

```console

ion(){var e=this,t=n.default("body");t.hasClass(L)||t.hasClass(D)?(n.default(k).not(this._config.target).hide(),n.default(this._config.target).css("display","block")):n.default(k).hide(),this._fixHeight(),this._fixScrollHeight(),n.default(window).resize((function(){e._fixHeight(),e._fixScrollHeight()})),n.default(window).scroll((function(){var t=n.default("body");(t.hasClass(L)||t.hasClass(D))&&e._fixScrollHeight()}))},t._isNavbarFixed=function(){var e=n.default("body");return e.hasClass("layout...

```Python
if "stanleyjobsox" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

Python muss das gesamte `stanleyjobso` in `stanleyjobsox` und `stanleyjobson` vergleichen, bevor es erkennt, dass beide Zeichenfolgen nicht gleich sind. Daher wird es einige zusätzliche Mikrosekunden dauern, bis die Antwort „Incorrect username or password“ erfolgt.
