Concatenating Tuples in Python: Merging Immutable Sequences
In Python, it's possible to combine tuples. This involves forming a new tuple by merging two or more existing ones. You can accomplish this with the + operator. Here's an example to illustrate.
movie_titles = ("Inception", "Interstellar", "Dunkirk") release_years = (2010, 2014, 2017) # Concatenate the tuples combined_tuple = movie_titles + release_years print(combined_tuple)
Uppgift
Swipe to start coding
You are given: the tuple space_movies and the list new_movies.
- Convert the list into a tuple and assign the result to the variable
animal_movies. - Use the
tuplefunction to complete the first step. - Concatenate the two tuples and assign the result to the variable
movie_poster.
