Keep in mind that in this case, FastAPI won't check the contents of the list.

For example, `list[int]` would check (and document) that the contents of the list are integers. But `list` alone wouldn't.

Beachten Sie, dass FastAPI in diesem Fall den Inhalt der Liste nicht überprüft.

Zum Beispiel würde `list[int]` überprüfen (und dokumentieren), dass der Inhalt der Liste Ganzzahlen sind. Aber `list` alleine würde das nicht.

Tenha em mente que, neste caso, o FastAPI não verificará o conteúdo da lista.

Por exemplo, `list[int]` verificaria (e documentaria) que os conteúdos da lista são inteiros. Mas `list` sozinho não.
