How to access elements from an array in Python

Onyejiaku Theophilus Chidalu

Overview

An array in Python is used to store multiple values or items or elements of the same type in a single variable.

We can access elements of an array using the index operator []. All you need do in order to access a particular element is to call the array you created. Beside the array is the index [] operator, which will have the value of the particular element’s index position from a given array.

Note that the value you pass into the index operator (the index position of the element you wish to access) must be an integer.

Example

# importing the array module
import array as arr

# creating an integer datatype array
x = arr.array('i', [1,2,3,4,5,6,7])

# to access the index 3 element 
print('The element in the index 3 of the array is: ', x[3])

# creating a float datatype array]
y =  arr.array('d', [1.5, 2.7, 3.5, 8.2, 6.9])

# to access the index 0 or the first element of the array
print('The element of the array in the index 0 of the float array is: ', y[0])

It is worth noting that in Python, the first character of a list, string, array etc., is of index 0.
