Diyelim ki  `name` değerine sahip `Person` sınıfınız var:

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Sonra bir değişkeni 'Person' tipinde tanımlayabilirsiniz:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

### Read env vars in Python

You could also create environment variables outside of Python, in the terminal (or with any other method), and then read them in Python.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

Ось чому, як сказано на офіційному сайті:

> Requests є одним із найбільш завантажуваних пакетів Python усіх часів

Використовувати його дуже просто. Наприклад, щоб виконати запит `GET`, ви повинні написати:

```Python
response = requests.get("http://example.com/some/url")
```

Відповідна операція *роуту* API FastAPI може виглядати так:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
     return {"message": "Hello World"}
