NumPy Tutorial #3: Array Indexing

In the previous blog, I have showed you how to create a NumPy array. In this blog, I will show you how to access data inside the array using index.

First of all, you can create a NumPy array for the example

import numpy as np

list_of_number = [1, 2, 3, 4, 5]

arr = np.array(list_of_number)

To get the data inside the array, you can use index to indicate the position of the data. For example, if you run this code

print(arr[2])

it will output

3

And if you run

print(arr[4])

you will get

5

Congratulations! you now know how to access data inside NumPy array using indexing. Thank you for reading this blog, see you next time!
