In the past, Python developers referred to this feature as tuple unpacking, but it became quite useful and popular among them. We need to pass five separate arguments to the function. Suppose we have a function that takes five arguments we create a list of five elements and pass it to the function, which will throw an error because elements are packed within the list. Python provides a unique feature to pack or unpack the arguments. In this tutorial, we will learn about the packing and unpacking of the arguments.

('Mean Streets', 'Martin Scorsese', 1973) ('The Age of Innocence', 'Martin Scorsese', 1993), ('Taxi Driver', 'Martin Scorsese', 1976), ('Jackie Brown', 'Quentin Tarantino', 1997), ('Pulp Fiction', 'Quentin Tarantino', 1994), ('Reservoir Dogs', 'Quentin Tarantino', 1992), Consider the following example: import random

We frequently use tuple unpacking to make code more readable.

('The Age of Innocence', 'Martin Scorsese'), # A list of movies represented as tuples (title, director) The real convenience of tuple unpacking is obvious when we use it to unpack tuples that are returned from a function: import random The result of this assignment is equivalent to the following: personal_id = '123456' We can also unpack a tuple (or any sequence, for that matter). We did it simply by listing several variables using commas: t = 'a', 10, 100.0 We have seen earlier how we can create a tuple by packing together a list of values.

Tuples often contain heterogeneous data, are returned as results of functions, and are often accessed by unpacking (see below).

Being immutable, tuples allow for runtime optimizaitions when storing, comparing, copying and assigning them to variables.

Being immutable, tuples are hashable, ie.

So why do tuples exist at all? There are several reasons: Unlike lists, tuples are immutable - once created, you can not assign values to individual elements of the tuple or add new elements to it.

min(s), max(s) - the smallest/the largest value in s.

s - simple indexing, returns the i-th element of the tuple.

s + t - return the concatenation of s and t.

x not in s - check if x is not equal to any elements in s.

x in s - check if x is equal to any elements in s.

Note that tuples implement all of the common sequence operations, such as: To access an element of a tuple, we use indexing, just like we would do with a list: city = ( # Without the comma, this does not create a tuple # You need the trailing comma even when using parentheses You might ask, if tuples are created as comma-separated, how do you create a single-element (singleton) tuple? It's simple: # Leave a trailing comma

Movie = ('Taxi Driver', 'Martin Scorsese', 1976) ('The Bronx', 'Brooklyn', 'Manhattan', 'Queens', 'Staten Island') # Tuples can contain mixed data types (even nested tuples) # We usually use parentheses when creating a tuple We create tuples by using a comma-separated list of values: # A dummy tuple

In Python, tuples are a sequence data type, very similar to lists.
