## Ejemplo
|
|
|
|
```python
|
|
# Datos aleatorios (alta entropia)
|
|
entropy_shannon(bytes(range(256)))
|
|
# ~8.0
|
|
|
|
# Datos repetitivos (baja entropia)
|
|
entropy_shannon(b"aaaaaaaaaa")
|
|
# 0.0
|
|
|
|
# Texto normal
|
|
entropy_shannon(b"hello world")
|
|
# ~2.84
|
|
```

## Notas
|
|
|
|
Entropia alta (>7.5) sugiere datos cifrados o comprimidos. Entropia baja (<3) sugiere datos estructurados o repetitivos. Retorna 0.0 para datos vacios.
