Prerequisite:

• Declaration/creation of the Array
• Common Data Items and Methods of an Array in Python

Here are the examples to demonstrate how to access elements from the array

Example 1:

# Accessing elements from the array

# importing array module 
import array as arr 

# int array
arr1 = arr.array('i', [10, 20, 30, 40, 50, 60]) 

# accessing element of array 
print("arr1[0]: ", arr1[0]) 
print("arr1[3]: ", arr1[3]) 

# float array
arr2 = arr.array('d', [22.59, 33.32, 43.32]) 

# accessing elements of array 
print("arr2[1]: ", arr2[1]) 
print("arr2[2]: ", arr2[2]) 

Output

arr1[0]:  10
arr1[3]:  40
arr2[1]:  33.32
arr2[2]:  43.32

Example 2:

# importing array module
import array as arr

# declaring int array
arr = arr.array('i', [20, 40, 60, 80])

print("First element  arr[0] :", arr[0])
print("Second element arr[1] :", arr[1])
print("Third element  arr[2] :", arr[2])
print("Fourth element arr[1] :", arr[3])
print()

print("Last element arr[-1]:", arr[-1])
print("Second last element arr[-2]:", arr[-2])

Output

First element  arr[0] : 20
Second element arr[1] : 40
Third element  arr[2] : 60
Fourth element arr[1] : 80
Last element arr[-1]: 80
Second last element arr[-2]: 60
