Now, we've delved into the most intriguing aspect: What is a two-dimensional array?

In general, two-dimensional arrays are called matrices—mathematical structures consisting of rows and columns. If it makes it easier to understand, you can visualize a matrix as a table.

Now, it's time to practice with 2D arrays. Let's explore how to create a 2-D array containing two arrays: 5.2, 3.0, 4.5 and 9.1, 0.1, 0.3:


              
12345

            
import numpy as np
# Creating array
arr = np.array([[5.2, 3.0, 4.5], [9.1, 0.1, 0.3]])
# Displaying array
print(arr)
copy
