How To Combine 3 Arrays In Python

Combining arrays is a common operation in Python, especially when working with big datasets. In this tutorial, we will show you how to combine 3 arrays in Python.


Step 1: Define the arrays

Let’s create 3 arrays a, b, and c.

Step 2: Combine the arrays

There are a few ways to combine arrays in Python. We will use the extend method to add b and c to a.

Step 3: Print the merged array

Let’s print the merged array to make sure the operation was executed correctly.


In this tutorial, we learned how to combine 3 arrays in Python using the extend method. This method works well when you have a small number of arrays to combine. If you have a larger number of arrays, you may want to consider using the concatenate method. Overall, combining arrays is a useful operation that can help simplify your code and make it more efficient.

Here is the full code:

The output of the code is:

[1, 2, 3, 4, 5, 6, 7, 8, 9]
