**SANGAT disarankan** agar kamu menulis atau menyalin kode, mengubahnya dan menjalankannya secara lokal.

Dengan menggunakannya di dalam editor, benar-benar memperlihatkan manfaat dari FastAPI, melihat bagaimana sedikitnya kode yang harus kamu tulis, semua pengecekan tipe, pelengkapan otomatis, dll.

## Install FastAPI

Langkah pertama adalah dengan meng-install FastAPI.

* finde das Modul `dependencies` (eine imaginäre Datei unter `app/routers/dependencies.py`) ...
* und importiere daraus die Funktion `get_token_header`.

Aber diese Datei existiert nicht, unsere Abhängigkeiten befinden sich in einer Datei unter `app/dependencies.py`.

Erinnern Sie sich, wie unsere Anwendungs-/Dateistruktur aussieht:

Sie können im Docstring <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a> schreiben, es wird korrekt interpretiert und angezeigt (die Einrückung des Docstring beachtend).
