## Das Theme ändern

Auf die gleiche Weise könnten Sie das Theme der Syntaxhervorhebung mit dem Schlüssel `syntaxHighlight.theme` festlegen (beachten Sie, dass er einen Punkt in der Mitte hat):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

Obige Konfiguration würde das Theme für die Farbe der Syntaxhervorhebung ändern:
