Data structures – Tuples

A tuple in Python is a sequence of objects.

They are used when we want to treat a sequence as a single object.

Examples of tuples can be the coordinates (x, y) or the definition of a color with its red, blue and green components (r, g, b)

The tuples are immutable, that is, they are constants that cannot be modified.

They are defined as a sequence of objects separated by commas and enclosed in parentheses.


xy = (10.20)

color = (10,20,30)

Operations between tuples

+ concatenates two tuples

* repetition of a tuple

[] select an element from the tuple


(2.3) + (5.6)

the tuple will be obtained (2,3,5,6)

2 * (1,2)

the tuple (1,2,1,2) will be obtained

t = (1,2)

t [1] = 2

Comparison operations are evaluated for each element in the tuple.


(1.2) <(3.4)

evaluates to True. Actually compare 1 <2 and 2 <4


In python there is multiple assignment that allows assigning values ​​to different variables online


x, y = (5.6)

would assign x = 1 y = 6

Default operations

sum (tuple) – sum all the elements of the tuple

max (tuple) – maximum element

len (tuple) – returns the number of elements
