#### Operasi

"Operasi" di sini merujuk ke salah satu dari metode HTTP berikut.

Salah satu dari:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...dan operasi lainnya yang unik:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

Dalam protokol HTTP, anda bisa berkomunikasi ke setiap path menggunakan satu (atau lebih) metode di atas.

---

* Validasi data.
* Annotasi API dan dokumentasi otomatis.

Semua itu anda hanya perlu mendeklarasikan sekali saja.

Fitur utama FastAPI:

* **Cepat**: Performa sangat tinggi, setara **NodeJS** dan **Go** (berkat Starlette dan Pydantic). [Salah satu *framework* Python tercepat yang ada](#performa).
* **Cepat untuk coding**: Meningkatkan kecepatan pengembangan fitur dari 200% sampai 300%. *
* **Sedikit bug**: Mengurangi hingga 40% kesalahan dari manusia (pemrogram). *

Bạn viết chuẩn Python với kiểu dữ liệu như sau:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Sau đó có thể được sử dụng:
