Funktionen
Einführung
Als Data Scientist können Sie effizienter arbeiten, wenn Sie Funktionen schreiben. Anstelle von Kopieren und Einfügen ist es mit Funktionen möglich, häufige Aufgaben leistungsfähiger und allgemeiner zu automatisieren. Gegenüber dem Kopieren und Einfügen zeichnet sich das Schreiben einer Funktion durch drei große Vorteile aus:
- Einer Funktion können Sie einen evokativen Namen geben, der Ihren Code verständlicher macht.
- Wenn sich die Anforderungen ändern, brauchen Sie den Code nur an einer Stelle zu ändern und nicht an vielen Stellen.
- Die Chance, identische Fehler durch Kopieren und Einfügen zu machen (das heißt, eine Variable an einer Stelle aktualisieren, aber nicht an einer anderen), verschwindet.
