Sie können ein Attribut als Kindtyp definieren, zum Beispiel eine Python-`list`.

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Das bewirkt, dass `tags` eine Liste ist, wenngleich es nichts über den Typ der Elemente der Liste aussagt.

## Listen mit Typ-Parametern als Felder { #list-fields-with-type-parameter }

Aber Python erlaubt es, Listen mit inneren Typen, auch „Typ-Parameter“ genannt, zu deklarieren.

        var i = 0
        val parts = line.split(Regex(" ")).toTypedArray()

        val element = WebPlatformUrlTestData()
        element.input = unescape(parts[i++])

        val base = if (i < parts.size) parts[i++] else null
        element.base =
          when {
            base == null || base.isEmpty() -> list[list.size - 1].base
            else -> unescape(base)
          }
