Summary  
This chapter covers how to merge immutable sequence types by concatenating tuples using the `+` operator to produce a new sequence.

General domain of usage  
Data processing and manipulation


En Python, es posible combinar tuplas. Esto implica formar una nueva tupla al fusionar dos o más existentes. Puedes lograrlo utilizando el operador `+`. Aquí tienes un ejemplo para ilustrarlo.

movie_titles = ("Inception", "Interstellar", "Dunkirk")
release_years = (2010, 2014, 2017)

# Concatenate the tuples
combined_tuple = movie_titles + release_years

print(combined_tuple)

Explora las estructuras de datos fundamentales del lenguaje de programación Python, incluyendo listas, diccionarios, tuplas y conjuntos, y aprende cómo aplicarlas de manera efectiva para resolver desafíos de programación del mundo real.

¿Qué es una lista? Una lista es una colección ordenada que puede modificarse. También permite elementos duplicados.
