Qué son y cómo usar Slices en Python - Luis Llamas

Uso de índices negativos. Python permite usar índices negativos para referirse a elementos relativos final de la secuencia (en lugar que desde el principio).. Parece un poco complicado, y al principio lía un poco. Pero básicamente, ultimos_tres = numeros[-3:] # Extrae los últimos tres elementos primeros_salvo_tres = numeros[:-3] # Extrae los elementos, salvo los tres últimos

List slicing in Python

With Python's slicing syntax, the first item is the start index, and the second item is the stop index.The start index is inclusive, but the stop index is exclusive, meaning Python stops just before the stop index..
