# Python Veri Tiplerine Giriş

Python isteğe bağlı olarak "tip belirteçlerini" destekler.

 **"Tip belirteçleri"** bir değişkenin <abbr title="örneğin: str, int, float, bool">tipinin</abbr> belirtilmesine olanak sağlayan özel bir sözdizimidir.

Değişkenlerin tiplerini belirterek editör ve araçlardan daha fazla destek alabilirsiniz.

Por esta razón, es común proporcionarlas en variables de entorno que son leídas por la aplicación.

/// tip | Consejo

Para entender las variables de entorno, puedes leer [Variables de Entorno](../environment-variables.md){.internal-link target=_blank}.

### `///` admonitions

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).

- `/// note | Технічні деталі`
- `/// tip | Порада`
- `/// warning | Попередження`
- `/// info | Інформація`

- response (HTTP): 响应
- path operation: 路径操作
- path operation function: 路径操作函数

- `/// warning | 警告`
- `/// info | 信息`
