Python Data Structures

Creating a Tuple

In Python, a tuple is a data structure that consists of a sequence of values enclosed in parentheses, with elements separated by commas. Tuples are similar to lists, but the key distinction is that tuples are immutable data structures.

Immutable data structures can't be modified after they're created. Tuples, just like lists, can hold any number of elements, and the data type of each element can vary. It's crucial to note that a tuple with only one element is defined with a comma following the element, as shown:


              12
            
single_movie = ("Inception",)  # Single-element tuple
print(single_movie)

Note

Without the comma, Python will interpret the parentheses as regular grouping, not as a tuple.


              12
            
not_a_tuple = ("Inception")
print(type(not_a_tuple))

Let's explore how to create tuples.

Creating an empty tuple


              12
            
empty_tuple = ()
print(empty_tuple)

Creating a tuple using the `tuple()` function

The tuple() function converts an iterable into a tuple. For example, you can convert a string into a tuple of its characters:


              12
            
movie_title = tuple("Inception")
print(movie_title)

Creating a tuple from a list

You can also use the tuple() function to create a tuple from a list:


              123
            
movie_list = ["Inception", "Interstellar", "Tenet"]
movies_tuple = tuple(movie_list)
print(movies_tuple)

Task

Create a tuple named movie_details that stores the title, director, release year, and genre of a movie (e.g., "Inception", "Christopher Nolan", 2010, "Science Fiction").
