Es hat **Vorteile** und **Nachteile** im Vergleich zu gängigen **Web-APIs**.

Wiegen Sie ab, ob die **Vorteile** für Ihren Anwendungsfall die **Nachteile** ausgleichen. 🤓

## GraphQL-Bibliotheken

Hier sind einige der **GraphQL**-Bibliotheken, welche **ASGI** unterstützen. Diese könnten Sie mit **FastAPI** verwenden:

  static final Iterable<Integer> ALL_INTEGER_CANDIDATES;

  static {
    ImmutableSet.Builder<Integer> intValues = ImmutableSet.builder();
    // Add boundary values manually to avoid over/under flow (this covers 2^N for 0 and 31).
    intValues.add(Integer.MAX_VALUE - 1, Integer.MAX_VALUE);
    // Add values up to 40. This covers cases like "square of a prime" and such.
    for (int i = 1; i <= 40; i++) {

```

Das war's.

Das sind die „Typhinweise“:

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial002.py!}
```

Das ist nicht das gleiche wie das Deklarieren von Defaultwerten, wie es hier der Fall ist:

```Python
    first_name="john", last_name="doe"
```

Das ist eine andere Sache.

Wir verwenden Doppelpunkte (`:`), nicht Gleichheitszeichen (`=`).

    if (mostRecentTrimFailed || mostRecentRebuildFailed) {
      // The OS has become our enemy! If the trim job failed, it means we are storing more data than
      // requested by the user. Do not allow edits so we do not go over that limit any further. If
      // the journal rebuild failed, the journal writer will not be active, meaning we will not be
      // able to record the edit, causing file leaks. In both cases, we want to retry the clean up

Hier finden Sie die einführenden Kapitel und Tutorials zum Erlernen von **FastAPI**.

**FastAPI** kullanmayacak olsanız bile tür belirteçleri hakkında bilgi edinmenizde fayda var.

/// note | "Not"

Python uzmanıysanız ve tip belirteçleri ilgili her şeyi zaten biliyorsanız, sonraki bölüme geçin.

## Motivasyon

Basit bir örnek ile başlayalım:

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

Programın çıktısı:

```

/// tip | "Tipp"

Sie erinnern sich vielleicht, dass Requestbodys ebenfalls mit Pydantic-Modellen deklariert werden.

Weil Sie `Depends` verwenden, wird **FastAPI** hier aber nicht verwirrt.
