Python Arrays Example

In this tutorial, we will learn about how to declare an array, its methods and attributes along with the working examples of it.

Arrays Examples:

The arrays class of arrays module in Python offers methods to process the arrays easily. The programmers can easily perform certain operations by using these methods. We should understand that a method is similar to a function that performs a specific task. But methods are written inside a class whereas a function can be written inside or outside the class. Methods are generally called as: objectname.method(). Please see Table for methods that can be used on arrays:

we can also use the following variables of Array class as shown in Table

Python program to understand various methods of arrays class.

from array import* 
arr = array('i', [10,20,30,40,50,20]) 
print('Original array:', arr) 
arr.append(30) 
arr.append(60) 
print('After appending 30 and 60:', arr) 
arr.insert(1, 99) 
print('After inserting 99 in 1st position:', arr) 
arr.remove(20) 
print('After removing 20:', arr) 
n = arr.pop() 
print('Array after using pop():', arr) 
print('Popped element:', n) 
n = arr.index(30) 
print('First occurrence of element 30 is at:', n)
lst = arr.tolist() 
print('List:', lst) 
print('Array:', arr)
