Wenn wir ein `dict` wie `user_dict` nehmen und es einer Funktion (oder Klasse) mit `**user_dict` übergeben, wird Python es „entpacken“. Es wird die Schlüssel und Werte von `user_dict` direkt als Schlüsselwort-Argumente übergeben.

Setzen wir also das `user_dict` von oben ein:

```Python
UserInDB(**user_dict)
```

so ist das äquivalent zu:

```Python
UserInDB(
    username="john",
    password="secret",

The Gradle codebase has evolved over time and has a mixture of simple getter/setter methods, Provider API and things in between.  It can be hard to follow best practices because Gradle provided types are reused in unexpected ways and extended by third party plugins.

Böylece duplicate veri içeren bir request alsanız bile, bu veri benzersiz öğelerden oluşan bir set’e dönüştürülür.

Ve bu veriyi ne zaman output etseniz, kaynakta duplicate olsa bile, benzersiz öğelerden oluşan bir set olarak output edilir.

Ayrıca buna göre annotate / dokümante edilir.
