## Was ist „Dependency Injection“

**„Dependency Injection“** bedeutet in der Programmierung, dass es für Ihren Code (in diesem Fall Ihre *Pfadoperation-Funktionen*) eine Möglichkeit gibt, Dinge zu deklarieren, die er verwenden möchte und die er zum Funktionieren benötigt: „Abhängigkeiten“ – „Dependencies“.

Então, no **FastAPI**, você pode utilizar uma classe Python como uma dependência.

O que o FastAPI realmente verifica, é se a dependência é algo chamável (função, classe, ou outra coisa) e os parâmetros que foram definidos.
