Let’s learn how to concatenate arrays in Numpy Python library.

Numpy concatenate

To join arrays in Numpy it is enough to know how to use concatenate Numpy function.

This is an example code to do that:

import numpy as np

my_array = np.array([[1, 5], [5, 4]])
my_array2 = np.array([[7, 4], [4, 8]])

joined_array = np.concatenate([my_array, my_array2])

print(f"This is my concatenated array: \n {joined_array}")

Thanks to Numpy concatenate function two arrays has been joined into one joined_array.
