### Oparcie o standardy open

Eğer Python type hintlerini bilmiyorsan veya bir hatırlatmaya ihtiyacın var ise(FastAPI kullanmasan bile) şu iki dakikalık küçük bilgilendirici içeriğe bir göz at: [Python Types](python-types.md){.internal-link target=_blank}.

Standart Python'u typelarını belirterek yazıyorsun:

```Python
from typing import List, Dict
from datetime import date

from pydantic import BaseModel

# Değişkeni str olarak belirt

Dans ce cas, l'URL serait : `/files//home/johndoe/myfile.txt`, avec un double slash (`//`) entre `files` et `home`.
