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.

Untuk tutorial, kamu mungkin hendak meng-installnya dengan semua pilihan fitur dan dependensinya:
