Thanks so much for all the support! We're approaching 5k subscribers. THAT'S AWESOME! You all make me want to keep creating better and better content. Thanks for all the encouraging words.
*****************************************************************
Full code from the video:

import numpy as np

Creation of a sample array
array_a = np.array([1,2,3,4,5])
print(array_a)

We can add elements of multiple data types to python lists, not arrays
print([1,2,3,4,5, 'derrick'])

print(array_a.shape) # View the shape of an array by the shape attribute

array_b = np.array([[1,2,3,4,5],[1,2,3,4,5]]) # Multidimensional arrays
print(array_b.shape)
