### Starten

Führen Sie den Server aus:

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]

///

## Es in der automatischen API-Dokumentation ansehen

Führen Sie nun `uvicorn` aus, indem Sie das Modul `app.main` und die Variable `app` verwenden:

<div class="termy">

```console
$ uvicorn app.main:app --reload

Sie können die Funktion ohne FastAPI an **anderen Stellen aufrufen**, und es wird **wie erwartet funktionieren**. Wenn es einen **erforderlichen** Parameter gibt (ohne Defaultwert), und Sie führen die Funktion ohne den benötigten Parameter aus, dann wird Ihr **Editor** Sie das mit einem Fehler wissen lassen, und **Python** wird sich auch beschweren.

and when she had got its head down, and was going to begin again,
it was very provoking to find that the hedgehog had unrolled
itself, and was in the act of crawling away:  besides all this,
there was generally a ridge or furrow in the way wherever she
wanted to send the hedgehog to, and, as the doubled-up soldiers
were always getting up and walking off to other parts of the
ground, Alice soon came to the conclusion that it was a very

An explicit floating-point type <a href="#Conversions">conversion</a> rounds to
the precision of the target type, preventing fusion that would discard that rounding.
