Patrones idiomáticos de Python, estándares PEP 8, type hints y buenas prácticas para construir aplicaciones Python robustas, eficientes y mantenibles.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Patrones de Desarrollo Python
Patrones idiomáticos de Python y buenas prácticas para construir aplicaciones robustas, eficientes y mantenibles.
## Cuándo Activar
- Escribir código Python nuevo
- Revisar código Python
- Refactorizar código Python existente
- Diseñar paquetes/módulos Python
## Principios Fundamentales
### 1. La Legibilidad Cuenta
Python prioriza la legibilidad. El código debe ser obvio y fácil de entender.
```python
# Bien: Claro y legible
def get_active_users(users: list[User]) -> list[User]:
"""Retorna solo los usuarios activos de la lista proporcionada."""
return [user for user in users if user.is_active]
# Mal: Inteligente pero confuso
def get_active_users(u):
return [x for x in u if x.a]
```
### 2. Explícito es Mejor que Implícito
Evitar la magia; ser claro sobre lo que hace el código.
```python
# Bien: Configuración explícita
import logging
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)
# Mal: Efectos secundarios ocultos
import some_module
some_module.setup() # ¿Qué hace esto?
```
### 3. EAFP - Es Más Fácil Pedir Perdón que Permiso
…
The line at the top of this page pins the label git:20260607.ac0f11c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
