## 範例

### 建立

- 建立一個 python 檔案 `main.py`，並寫入以下程式碼：

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

## Exemplo { #example }

### Crie { #create-it }

Crie um arquivo `main.py` com:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

* Валідація **складних структур**:
    * Використання ієрархічних моделей Pydantic. Python `typing`, `List` і `Dict` тощо.
    * Валідатори дозволяють чітко і просто визначати, перевіряти й документувати складні схеми даних у вигляді JSON-схеми.
